Introduction

The F2923 is a low insertion loss 50Ω SP2T absorptive RF Switch designed for a multitude of wireless and other RF applications. This device covers a broad frequency range from 300 kHz to 8000 MHz. In addition to providing low insertion loss, industry leading isolation at 2 GHz and excellent linearity, the F2923 also includes a patent pending constant impedance (K_Z) feature. K_Z minimizes LO pulling in VCOs and reduces phase and amplitude variations in distribution networks. It is also ideal for dynamic switching/selection between two or more amplifiers while avoiding damage to upstream/downstream sensitive devices such as PAs and ADCs. The F2923 uses a single positive supply voltage of 3.3 V supporting three states using either 3.3 V or 1.8 V control logic. An added feature includes a ModeCTL pin allowing the user to control the device with either 1-pin or 2-pin control.
