SKYA21037

RF Switches Overview

The SKYA21037 is an advanced CMOS Silicon-On-Insulator (SOI) Double-Pole Double-Throw (DPDT) radio frequency switch designed for automotive applications. It operates within a frequency range of 0.7 GHz to 3.8 GHz and meets AEC-Q100 Grade 2 standards. The device features low insertion loss ranging from 0.45 dB to 0.55 dB and provides high isolation between 28 dB and 29.5 dB. Key performance metrics include a P1dB compression point of 38.5 dBm (7.07 Watts) and an IIP3 of 70 dB. It utilizes a single control input with a voltage range of 1.35 V to 3.1 V, eliminating the need for external DC blocking capacitors when no external DC voltage is applied.
