Patent ID: 8729949

Claim:
A radio frequency (RF) device comprising: a transmit circuit configured to provide an RF signal including transmit information; an antenna configured to transmit the RF signal; and a microwave switch configured to provide a switching path between the antenna and the transmit circuit and including at least one switching FET configured to conduct the RF signal between the transmit circuit and the antenna in a first mode of operation, at least one shunt FET configured to shunt the RF signal to ground in a second mode of operation, and a plurality of control switches configured to turn on the at least one shunt FET in the second mode and to turn off the at least one shunt FET in the first mode, to turn off the at least one switching FET in the second mode and to turn on the at least one switching FET in the first mode, to increase a voltage difference between a gate and a drain of the at least one switching FET, and to increase a voltage difference between a gate and a drain of the at least one shunt FET, the at least one switching FET including an intergate electrode disposed between a pair of switching FET gate contacts to bias an intergate region to adjust a characteristic of the at least one switching FET, a first feed-forward resistor electrically coupled to the drain of the at least one switching FET and the intergate electrode, and a second feed-forward resistor coupled to a source of the at least one switching FET and the intergate electrode.
