A switch circuit including a first differential amplifier pair providing a portion of an isolation channel, a second differential amplifier pair providing a portion of a transmit channel, and a third differential amplifier pair providing a control bias for selecting either the transmit channel or the isolation channel. The switch circuit provides 35 dB isolation between input and output over a 15 GHz-26 GHz range, yet is only 500 mum by 250 mum in size.
