For airborne surveillance and similar applications, Custom Microwave Components offers a broadband distribution matrix that switches any of 80 octave-band inputs to any of five outputs (non-blocking). The output frequency range covers 100 MHz to 18 GHz. The signal path from input to output has a nominal gain of 0 dB with less than 14 dB noise figure. Leakage across any of the channels is less than 60 dB. Paths can be grouped into sets that amplitude and phase track. Channels can be selected within 2 µsec, and output blanking occurs in 100 nsec.
The 12U rack-mounted unit’s environmental operating range is 0 to +55°C, up to 95 percent relative humidity, vibration meeting Mil-STD-810F Method 514.5 and 50,000 foot altitude.
First developed in 2003, the distribution matrix has a history of reliable service. The RF units are line replaceable, enabling field service and upgrades, if required. The design allows user-defined controls, which provides additional flexibility.
