GENERAL DESCRIPTION

The ADRF5042 is a nonreflective SP4T switch manufactured in

the silicon on insulator (SOI) process.

The ADRF5042 operates from 100 MHz to 44 GHz with an

insertion loss of lower than 3.2 dB and an isolation of higher

than 35 dB. The device has a RF input power handling

capability of 24 dBm for both through and terminated paths.

The ADRF5042 requires a dual-supply voltage of +3.3 V and

−3.3 V. The device employs CMOS- and low voltage transistor

to transistor logic (LVTTL)-compatible controls.

The ADRF5042 has enable and logic select controls to feature

all off state and port mirroring, respectively.

The ADRF5042 is pin compatible with the ADRF5043 low

frequency cutoff version, which operates from 9 kHz to 44 GHz.

The ADRF5042 comes in a 24-terminal, 3 mm × 3 mm, RoHS

compliant, land grid array (LGA) package and can operate from

−40°C to +105°C.
