GENERAL DESCRIPTION

The ADRF5021 is a general-purpose single-pole, double-throw

(SPDT) switch manufactured using a silicon process. It comes

in a 3 mm × 3 mm, 20-terminal land grid array (LGA) package

and provides high isolation and low insertion loss from 9 kHz

to 30 GHz.

This broadband switch requires dual supply voltages, +3.3 V

and −2.5 V, and provides CMOS/LVTTL logic-compatible

control.
