Claim Text:
1. An integrated circuit comprising: a transmit/receive (T/R) circuit configured to transmit and receive radio frequency (RF) signals; and a gate/drain bias control circuit configured to enable or disable internal gate switching of one or more amplifiers of said transmit/receive (T/R) circuit in response to a first control signal, wherein (i) when said first control signal is in a first state, one or more power amplifiers in a transmit path of said transmit/receive (T/R) circuit and one or more low noise amplifiers in a receive path of said transmit/receive (T/R) circuit are switched using internal gate switching and (ii) when said first control signal is in a second state, said internal gate switching is disabled to allow said one or more power amplifiers in said transmit path of said transmit/receive (T/R) circuit and said one or more low noise amplifiers in said receive path of said transmit/receive (T/R) circuit to be enabled and disabled solely by external drain switching.
