Overview: F2914
High Reliability SP4T RF Switch, 50MHz to 8000MHz Datasheet The F2914 is a high reliability, low insertion loss, 50Ω SP4T absorptive RF switch designed for a multitude of RF applications including wireless munications. This device covers a broad frequency range from 50MHz to 8000MHz. In addition to providing low insertion loss, the F2914 also delivers excellent linearity and isolation performance while providing a 50Ω termination to the unused RF input ports. The F2914 also includes a patent pending constant impedance (KZ) feature. KZ 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 PAs and ADCs.
The F2914 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 bees the negative supply.
