DC to 12 GHz, Differential, Nonreflective, Silicon SPDT Switch

The ADRF5203 is a silicon, differential, single-pole double-throw (SPDT) switch. The ADRF5203 operates from DC to 12 GHz with an insertion loss of better than 1 dB and an isolation higher than 38 dB. The device has a DC voltage input range of ±8 V and RF input power handling of differential 31 dBm for through paths and 24 dBm for terminated paths.

The ADRF5203 operates with dual-supply voltages of ±12 V. The ADRF5203 employs complementary metal-oxide semiconductor (CMOS)- and low voltage transistor logic (LVTTL)-compatible controls. The ADRF5203 has an enable control to feature all off state function. The High-Z control selects the termination on the unselected RF channel.

The ADRF5203 comes in a 22-terminal, 3 mm × 3 mm, RoHS compliant, land grid array (LGA) package and can operate from −40°C to +105°C.
