Millennium Microwave Corporation manufactures and markets the following two main product groups; Sub-Systems and Switching Systems Products. These two product lines each have their own distinctive characteristics and serve the needs of two different marketplaces.
Subsystems Products
Subsystem Products incorporate multiple functions into a single integrated assembly. Millennium Microwave Corporation has the technical capability to manufacture and integrate switches, filters, amplifiers, etc. and other components to provide customers with a quality, high performance cost-effective solution. The integrated solution usually yields a product that performs better than individual components combined. Subsystems products provided by Millennium Microwave Corporation include:
Switched filter banks
Solid –state switches
Integrated assembliesSwitching Systems
Switching systems are electronic systems that are used to route signal to specific output ports under defined control of the customer. Most switching systems are specified to include an “on-board” computer (CPU chip) that allows remote control and fully automatic operation. Switching systems, also known as Switch Matrix products are used whenever there is a need to connect multiple signal inputs to multiple signal outputs or one input to multiple outputs. There are several switching technologies employed to accomplish the task of signal routing including:
Solid-state PIN diode switch matrices
Solid-state GaAs MMIC switch matrices
Electromechanical and relay switch matrices
Engineering design is the strength of Millennium Microwave Corporation. Our design engineering staff works closely with our customers to achieve an optimum design and a cost-effective solution. Our engineers bring a wealth of experience and utilize the latest available commercial and proprietary CAD software. Reliability of our products is enhanced by the careful selection of components, materials and processes.
Millennium Microwave Corporation products follow a rigid, well-defined manufacturing flow. All processes are documented and include the necessary controls to ensure a successful result. Our operation includes standard hybrid processes such as wire bonding, parallel-gap resistance welding and epoxy die attach.
Many of the products we provide to the defense industry are required to meet stringent environmental and reliability requirements. Typically these are required to adhere to the strict visual and screening requirements of MIL-STD-883. Most of our products can be provided with a hermetic seal using a laser welding process.

Switched filter banks are useful devices, which find applications in areas such as receiver systems, test sets, EW systems, etc. The switched filter bank offers the system designer a great advantage in performance, size and cost over the use of separate switches and filters. The integrated approach of the switched filter bank eliminates the problems associated with interconnection and results in a product with lower loss, lower ripple, lower resultant VSWR, smaller size, and reduced cost.

The block diagram of a typical N Channel switched filter bank.
.A switched filter bank generally consists of three major subassemblies:
| Filters | The filters used in the switched filter bank can be of various types and configurations. Standard designs are available as well as custom configurations to fit unique system requirements. |
| Switches | The switch assembly connects the RF input and RF output to the appropriate filter and contains all microwave-switching elements. |
| Driver, sub-assembly | The driver/assembly is the interface between the user and the switched filter bank. Basically, it converts a logic code supplied by the user, and sends signals to the switches in order to connect and/or disconnect switch arms in the appropriate manner. |
The switched filter bank is operated by applying correct logic code to the control pins. The switched filter bank will then connect one of the filters between the RF input and the RF output, and the other filters will be disabled. The system engineer can therefore select any one of the N filters for insertion between the RF input and the RF output.
Consider the following block diagram of a typical switched filter bank shown in below.
RF energy enters the switched filter bank at the RF input. Each filter has its own specified pass band and refection characteristics. Application of the digital code 100 in this example will enable the correct arm of SW1 and SW2 and allow RF energy to pass through filter 1. This effectively connects filter 1 between the RF input and RF output. In addition, Filters 2 and 3 are disabled. These filters are isolated by the "off" arms of the switches above.
| The RF output of the switched filter bank with application of control state 1 input code is shown in figure 4. | |||||||
|
|
|||||||
| Likewise, application of control state 2 would
connect Filter 2 (bandpass frequency of 11.8 14.2GHz,) control state 3
connects filter 3 (bandpass frequency of 13.8 - 16.2 GHz) and control
state 4 will result in the all-off condition. Figures 5 through 7 represent typical output responses for the switched filter bank with application of control states 2 through 4 respectively. |

Millennium Microwave offers a complete line of solid state switch
matrix products. We can choose from a number
of solid state switch technologies such as silicon PIN diode, Gallium
Arsenide MMIC, CMOS, and relay to find the
best solution to your switching requirement. All Millennium Microwave
Corporation switch matrix products are provided
with an on-board Central Processing Unit and can be controlled remotely
using GPIB and RS-232.
The company produces solid state switch matrix systems in non-blocking
and full-fanout configurations:
* Multiple Output: A single input can be connected to multiple
outputs.
* Non-Blocking: Allows multiple inputs to connect to multiple outputs;
however, each input can be connected to
only one output at a given time.
* Full Fanout: In a full fanout switch matrix, a single input can be
connected to any, all, or a combination of
outputs simultaneously.
* Zero Loss: This switch matrix features an internal RF amplifier to
offset the switch loss and provides a system
with 0 dB insertion loss.
Regardless of the frequency in which you are operating, Millennium
Microwave Corporation has a product to meet
your requirements.
There are several switch technologies the customer may choose from. Each have properties desirable from application to application, as well as frequency limitations.
Silicon PIN Diode- As reliable as digital circuitry yet able to pass frequencies greater than 18 GHZ, these diodes are versatile as well as dependable.
Gallium Arsenide MMIC- Integrated Circuit composed of low power consuming GaAs Field Effect Transistors are the economical choice when applications spanning DC to 2 GHZ are needed.
CMOS Switches- The space saver, for low frequency application you can maximize the space you have available by utilizing CMOS matrix chips. Currently 32 x 32 system is available in a 5 1/4" chases.
Reed Relay- For low insertion loss and minimal distortion this is the electro mechanical solution.
Refer to the charts below to evaluate application needs vs the switch technologies' properties listed below:

Things to consider when selecting the technology:
Generally the
higher the frequency, the poorer the performance of the technology
Generally Quality
of Response and Cost are proportional.
Almost any configuration is possible, however, certain configurations are more common and are listed below:
Connects one input to N outputs.
Multiple 1XN Multiple 1XN matrices controlled by a common computer.
Connects N input to M outputs.
Connects N inputs to any and all of M outputs; can connect an input
to any or all outputs simultaneously.
Usually the
customer has more in mind than just a simple
matrix. They have a concept..."I have 4 recievers supplying my station
with both horizontal and vertical signals.
I need the six signals to go to a monitoring analyzer, as well as, 10
remote destinations. Because signal strengths
may flucuate, I want a the ability to adjust the signal strength with
attenuators a maximum of 20dB in 1dB increments.
The system should not cause any loss to my signals when the attenuation
is set at 0dB."
This customer requirement is more involved than the standard matrix
configurations mentioned earlier and requires
a unique custom solution. Millennium Microwave Corp. can integrate this
complete system for the customer, saving
space, labor, and time.
Many times, to avoid determining system minimums for intermodulation
and noise, customers choose to purchase passive
units that do not employ amplifiers. If insertion loss is an issue,
then configurations above may include amplifiers.
The customer should consider Power @ 1dB compression, intercept points,
noise figure, and input signal range requirements.
Attenuators (digital and fixed), isolators, and couplers can be
integrated into units to meet customer particular
requirements.
Offers integration of various components (amplifiers, power dividers, couplers, etc) into single assembly
Feature state-of-the art switch performance
Designs are optimized to customers’ specific requirements
Integration offers higher performance solution then “bolting together”
individual components.
