Product Details

The ADRF5043 is a non-reflective, single pole, four-throw (SP4T) switch manufactured in the silicon process (SOI).

The ADRF5043 operates from 9 kHz to 44 GHz with insertion loss of lower than 3.0 dB and isolation of higher than 35 dB. The device has a radio frequency (RF) input power handling capability of 24 dBm for both through and terminated paths.

The ADRF5043 requires a dual-supply voltage of +3.3 V and −3.3 V. The device employs complimentary metal-oxide semiconductor/low-voltage transistor-transistor logic (CMOS/LVTTL) logic-compatible controls.

The ADRF5043 has enable and logic select controls to feature all off state and mirror port selection respectively.

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.
