Model No. A35-MX141 is an absorptive switch
matrix consisting of 36 RF input/output connectors
with two SP18T absorptive RF switches as the basic
building blocks. Using a single RFconnector, it allows
either a transmitter or receiver to connect to 36 different
array elements. Phase matching of +/- 8o is from
any of the 16 input ports to any of the 12 output ports. The input signals are launched through a precision, high performance 2.0 dB attenuator and a mechanical adjustable phase shifter. The unit is fed using a phase matched cable to an Integrated Microwave Assembly (IMA). Microwave Assembly consists of SP5T(70 dB isolation), a medium power, low noise ampli er, a VVA for temperature compensation of ampli er andswitch circuits.
