Abstract

A FEM includes a transmit amplifier (405) comprising a first transistor and a second transistor coupled between first and second differential nodes, a receive amplifier (415) comprising a third transistor and a fourth transistor coupled between the first and second differential nodes. The transmit amplifier (405) includes pseudo-differential input capacitively coupled with the first differential node and produces a differential output at the second differential node. The receive amplifier (415) includes a differential input capacitively coupled with the second differential node and produces a differential output cross-coupled with the first differential node. Common terminals for the receive amplifier (415) are selectively coupled with ground in receive mode and voltage supply in transmit mode. The receive amplifier (415) supplies a neutralizing feedback to the first differential node in transmit mode, and the transmit amplifier (405) supplies a neutralizing feedback to the second differential node in receive mode.
