1 / 22 page  Datasheet F2914 High Reliability SP4T RF Switch, 50MHz to 8000MHz X0007072 Rev.1.0 Dec.1.20 Page 1 Description The F2914 is a high reliability, low insertion loss, 50Ω SP4T 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 F2914 also delivers excellent linearity and isolation performance while providing a 50 Ω 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 becomes the negative supply. Functional Block Diagram Control Circuit RF4 RF2 RF1 V1 V2 V3 RFC 50 Ω 50 Ω 50 Ω RF3 50 Ω VSSEXT K|Z| Features • Four symmetric, absorptive RF ports • High Isolation: 50dB at 4000MHz • Low Insertion Loss: 1.1 dB at 4000MHz • High Linearity: o IIP2 of 114 dBm at 2000MHz o IIP3 of 60 dBm at 4000MHz • High Operating Power Handling: o 33 dBm CW on selected RF port o 27 dBm 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-pin QFN package • Pin compatible with competitors 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 K|Z| during switching transition • RFX to RFC Isolation = 50dB at 4GHz • Insertion Loss = 1.1 dB at 4GHz • IIP3: +60 dBm at 4GHz • Extended temperature: -40°C to +105°C 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 |
