Patent ID: 7239852

Claim:
A bi-directional amplifier having a first mode and a second mode comprising: a first port; a second port; a first amplification path electrically connected between the second port and the first port, biased to directionally couple a signal from the second port to the first port during the first mode and biased off during the second mode; a second amplification path electrically connected between the first port and the second port, biased to directionally couple a signal from the first port to the second port during the second mode and biased off during the first mode; said first mode is a receive mode and said first amplification path is a receiver amplifier which further comprises an input matching network and an output matching network for optimizing said receiver amplifier noise figure; said second mode is a transmit mode and said second amplification path is a transmitter amplifier, which is optimized for high power, further comprising a transmitter electrode that is biased at a high voltage potential when the transmitter amplifier is in the transmit mode; said transmitter amplifier further comprises an input matching and output matching network, and said receiver input and output matching networks topologies are asymmetrical to said transmitter input and output matching networks.
