<p>A switch circuit including a first differential amplifier pair (Q1, Q2) providing a portion of an isolation channel, a second differential amplifier pair (Q3, Q4) providing a portion of a transmit channel, and a third differential amplifier pair (Q5, Q6) providing a control bias for selecting either the transmit channel or the isolation channel. The switch circuit provides 35dB isolation between input and output over a 15GHz-26GHz range, yet is only 500µ by 250µ in size.</p> |
