1 / 21 page  High Reliability SP5T RF Switch 50MHz to 8000MHz F2955 Datasheet © 2018–2023 Renesas Electronics Corporation 1 November 1, 2023 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. Competitive Advantage The F2955 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. Constant impedance K|Z| during switching transition RFX to RFC isolation = 49dB at 4GHz Insertion loss = 1.1dB at 4GHz IIP3: +60.5dBm at 4GHz Extended temperature: -40°C to +105°C Typical Applications Base Station 2G, 3G, 4G Portable Wireless Repeaters and E911 Systems Digital Pre-distortion Point-to-Point Infrastructure Public Safety Infrastructure Military Systems, JTRS Radios Cable Infrastructure Test / ATE Equipment Features Five symmetric, absorptive RF ports High isolation: 49dB at 4000MHz Low insertion loss: 1.1dB at 4000MHz High linearity: • IIP2 of 114dBm at 2000MHz • IIP3 of 60.5dBm at 4000MHz High operating power handling: • 33dBm CW on selected RF port • 27dBm on terminated ports Single 2.7V to 5.5V supply voltage External negative supply option 3.3V and 1.8V compatible control logic Operating temperature: -40°C to +105°C 4 × 4 mm 24-QFN package Pin compatible with competitors Block Diagram Figure 1.
