The F2914 is a high reliability, low insertion loss, 50 Ω SP4T absorptive RF switch designed for a multitude of wireless and other RF applications.  This device covers a broad frequency range from 50 MHz to 8000 MHz.  In addition to providing low insertion loss, the F2914 also delivers excellent linearity and isolation performance while providing a 50 Ω termination to the unused RF ports.  The F2914 also includes a patent pending constant impedance (Kz) feature. Kz improves hot switching ruggedness, 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 F2914 uses a single positive supply voltage supporting three logic control pins using either 3.3 V or 1.8 V control logic. Connecting a negative voltage to pin 20 disables the internal negative voltage generator and becomes the negative supply.
