Abstract

A transceiver capable of operating over a frequency range of substantially 10 GHz to substantially 18 GHz, and comprising one or more multifunction monolithic microwave integrated circuits (MMICs) is provided. The transceiver preferably comprises a single multifunction MMIC, which comprises a switched attenuator, a low noise amplifier (LNA), a transmit/receive switch, a mixer and a local oscillator (LO) buffer amplifier. The transceiver preferably operates in two modes, a receive mode and a transmit mode. In the receive mode the noise figure of the transceiver is substantially 4 dB or less. In the receive mode the conversion gain of the transceiver is substantially 10 dB or more. In the transmit mode the insertion loss of the transceiver is substantially -12 dB. The size of the transceiver is substantially 30 mm2 or less. The transceiver port return losses are preferably greater than substantially 10 dB over at least a 10 GHz to 17 GHz frequency range.
