Overview
Description
The F2955 is a high reliability, low insertion loss, 50Ω SP5T absorptive RF switch designed for a multitude of RF applications, including wireless communications. This device covers a broad frequency range from 50MHz to 8000MHz. In addition to providing low insertion loss, the F2955 also delivers excellent linearity and isolation performance while providing a 50Ω termination to the unused RF input ports. The F2955 also includes a patent-pending constant impedance (K|z|™) feature. K|z| improves system 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 power amplifiers (PAs) and analog-to-digital converters (ADCs).
The F2955 uses a single positive supply voltage supporting three logic control pins using either 3.3V or 1.8V control logic. Connecting a negative voltage to pin 20 disables the internal negative voltage generator and becomes the negative supply.
