Abstract: A two-dimensional FET array (102) within a Q-band power amplifier module is presented. Array (102) has a plurality of substantially identical one-dimensional FET arrays (106) substantially centered upon a primary axis (130) of two-dimensional array (106) substantially perpendicular to a propagation axis (110) of module (100). Each one-dimensional array (106) is formed of a plurality of FETs (128) substantially centered along a FET axis (134) substantially parallel to propagation axis (110). Each one-dimensional array (106) is proximate and coupled to each of an input bus (136) and an output bus (138), both oriented substantially parallel to propagation axis (110).

Abstract: A complimentary switched amplifier transceiver (10) is provided which offers performance advantages and reduces system complexity over conventional half-duplex transceivers by using complimentary switched amplifiers for eliminating switches. Power output to a channel transition (31) from a transmit amplifier (26) is not degraded by a switch insertion loss in a transmit mode. Receiver noise figure is not degraded due to the switch insertion loss from the channel transition (31) to a receive amplifier (27). Switch devices and their associated control lines are eliminated, reducing circuit complexity for complimentary switched amplifier circuits such as a combined amplifier switch (12) and a first bi-directional amplifier (22).
