GENERAL DESCRIPTION

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 con-

trols. 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, 3mm × 3mm, RoHS com-

pliant, land grid array (LGA) package and can operate from −40°C

to +105°C.
