Abstract
A transmit/receive module includes an integrated control circuit that is configured to operate in transmit and receive modes. In the transmit mode, the integrated control circuit converts a digital input signal into a plurality of phase shifted RF transmit signals. In the receive mode, the integrated control converts an RF receive signal into a digital output signal. The transmit/receive module further includes a plurality of transmit/receive integrated circuits connected. Each of the transmit/receive integrated circuits amplify one of the RF transmit signals using a power amplifier during the transmit mode, and amplify one of the RF receive signals using a low noise amplifier during the receive mode. The integrated control circuit biases the power amplifier and calibrates a power level the power amplifier in the transmit mode. The integrated control circuit protects the integrated control circuit from damage by controlling the low noise amplifier during the receive mode.
