Abstract
A highly linear 9 throw switch for GSM/WCDMA applications with an IMD2/3 of -105 dBm at the control voltages starting as low as 2.8/0 V has been successfully developed. This high linearity performance was achieved using a backside bias technique which does not degrade the power handling capability of the device resulting in the harmonics performance below -35 dBm for VSWR 5:1 at the control voltages 3.2/0 V and TX/TRX losses below 0.9 dB at 2GHz.
