An apparatus includes a drain node, a plurality of source nodes and a gate node. The drain node may be configured to transfer a drain signal along a first axis from a first port to a second port. The source nodes may be (i) distributed along the first axis and (ii) configured to transfer a plurality of source signals along a second axis from the drain node to a ground node. The gate node may be (i) arranged in parallel to the drain node and (ii) configured to control the source signals in response to a gate voltage. The drain node, the source nodes and the gate node generally form a traveling-wave switch that blocks a slot mode current through the source nodes.

Traveling-wave switch with multiple source nodes

An integrated circuit includes a transmit/receive (T/R) circuit and a gate/drain bias control circuit. The transmit/receive (T/R) circuit may be configured to transmit and receive radio frequency (RF) signals. The gate/drain bias control circuit may be configured to enable or disable internal gate switching of one or more amplifiers of the transmit/receive (T/R) circuit in response to a first control signal. When the internal gate switching is disabled the one or more amplifiers of the transmit/receive (T/R) circuit are enabled and disabled solely by external drain switching.
