High Gain and Isolation Ka-Band Multi-Channel Receiver Unit

A compact four-channels high gain and high isolation receiver unit has been developed at Ka-band frequencies. A total of 48 input and output signals are present in the receiver unit: 15 RF signals, 16 differential control signals and 5 DC bias feeds. The receiver unit presents 30dB insertion gain, 7.5dB noise figure and over 32dB isolation between the transmitter and receiver paths with an overall transmission insertion loss of 2dB.
