Transmit-receive module for phased-array antennas

摘要: Coupling module for use with phased-array antenna systems. The includes separate phase shifters the transmit and receive paths through module. path also a power amplifier small signal, low noise amplifier. two are coupled to radiating element by transmit-receive switch or microwave circulator. A conducting septum is located between devices in increase isolation paths. individual optimized unidirectional flow of comparatively large signals degree desired shift resolution. By using vector modulators devices, amplitude signal can be compensated temperature frequency variations path.
