High Reliability SP4T RF Switch 400 MHz to 8000 MHz F2914 Product Brief, Rev A 10/15/2015 1 © 2015 Integrated Device Technology, Inc. GENERAL DESCRIPTION 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 400 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 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 3.3 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 F2914 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 KK||ZZ|| during switching transition  RFX to RFC Isolation = 50 dB*  Insertion Loss = 1.1 dB*  IIP3: +61 dBm*  Extended temperature: -40 °C to +105 °C * 4 GHz
