GENERAL DESCRIPTION
The ADRF5043 is a nonreflective, SP4T switch manufactured in
the silicon on insulator (SOI) process.
The ADRF5043 has enable and logic select controls to feature
all off state and port mirroring, respectively.
The ADRF5043 operates from 9 kHz to 44 GHz with an
insertion loss of lower than 2.5 dB and an isolation of higher
than 36 dB. The device has a RF input power handling
capability of 24 dBm for both through and terminated paths.
The ADRF5043 is pin compatible with the ADRF5042 fast
switching version, which operates from 100 MHz to 44 GHz.
The ADRF5043 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.
The ADRF5043 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.
