This paper designed a GaAs-based 2~6GHz Transmit/Receive Multi-function Chip. This chip integrated the transmit/receive switch, the receiving low noise amplifier and the transmitting power amplifier, which has high integration, low noise, high gain, high output power and high poweradded efficiency. The measurement shows that, at 2~6GHz,in the receive channel, the gain is 25dB, the NF less than 2.5dB, output P1dB power is 13.5dBm, the current less than 50mA;in the transmit channel, the gain over 28dB, the saturated output power over 23.5dBm, the power-added efficiency is 24%~38%, the current less than 230mA. The chip size is 3.0mm×2.2mm.
