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

The ADRF5203 is a silicon, differential, SPDT switch. The ADRF5203 operates from DC to 12GHz with an insertion loss of better than 1.1dB and an isolation higher than 37dB. The device has a DC input voltage range of ±8 V and RF input power handling of differential 31dBm for through paths and 24dBm for terminated paths.

The ADRF5203 operates with dual-supply voltages of ±12V. The ADRF5203 employs complementary metal-oxide semiconductor (CMOS)- and low voltage transistor logic (LVTTL)-compatible controls. The ADRF5203 has an enable control to feature its all off state function. The high-Z control selects the termination (100Ω or high-Z) 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.
