1 / 19 page  High Reliability SP5T RF Switch 50MHz to 8000MHz F2915 Datasheet © 2020 Renesas Electronics Corporation 1 June 22, 2020 DESCRIPTION The F2915 is a high reliability, low insertion loss, 50 Ω SP5T absorptive RF switch designed for a multitude of RF applications including wireless communications. This device covers a broad frequency range from 50 MHz to 8000 MHz. In addition to providing low insertion loss, the F2915 also delivers excellent linearity and isolation performance while providing a 50 Ω termination to the unused RF input ports. The F2915 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 F2915 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. COMPETITIVE ADVANTAGE The F2915 provides constant impedance in all RF ports during transitions improving a system’s hot-switching ruggedness. The device also supports high power handling, and high isolation; particularly important for DPD receiver use.
