F2923

Constant Impedance K|z| SP2T RF Switch

The F2923 is a low insertion loss 50Ω SP2T (SPDT) 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. 

Features

  • Constant Impedance K|z| during transition
  • Very low insertion loss: 0.48 dB @ 2 GHz
  • High Input IP3: 66 dB @ 2 GHz
  • RF1 / RF2 to RF_Com Isolation: 74 dB @ 2 GHz
  • 1-pin or 2-pin device control option
  • Low DC current: 127 µA using 3.3 V logic
  • Supports 1.8 V and 3.3 V control logic
  • Extended temperature: -55 °C to +105 °C
  • 4 mm x 4 mm, 20-pin TQFN package
  • Industry standard footprint and pin compatible with F2912
