报告简介：

This work demonstrated a fully balanced structure of wideband RF switch. The switch utilizes PIN diodes to form two balanced paths which transmit the RF signals in common mode and the drive signal of PIN diode in differential mode. The common-mode choke can be used to block AC signal and feed DC bias. It can also be used to suppress the transient voltage due to the drive signal. The switch achieved low insertion loss and high isolation within a bandwidth between 10MHz-100MHz. The switch also suppressed the transient voltage to less than 3.3mV with a very short dead time.
