Patent ID: 7728771

Claim:
A multi-channel, dual-band, radio frequency (RF) transmit/receive (T/R) module, comprising: a compact, RF manifold connector; and at least four T/R channels, each including: a notch radiator, a diplexer with an input port coupled to the notch radiator, an upper-band port and a lower-band port, a power amplifier, including at least one dual-band gain stage, coupled to the notch radiator, a low noise amplifier, including n lower-band gain stages arranged in series and coupled to the lower-band port of the diplexer and m upper-band gain stages arranged in series and coupled to the upper-band port of the diplexer, where m is greater than n, and a T/R cell, including a phase shifter, a signal attenuator and at least one dual-band gain stage, coupled to the power amplifier, the low noise amplifier and the manifold connector.
