Datasheet F2914 High Reliability SP4T RF Switch, 50MHz to 8000MHz Description Features The F2914 is a high reliability, low insertion loss, Four symmetric, absorptive RF ports 50 SP4T absorptive RF switch designed for a High Isolation: 50dB at 4000MHz multitude of RF applications including wireless Low Insertion Loss: 1.1 dB at 4000MHz communications. This device covers a broad High Linearity: frequency range from 50MHz to 8000MHz. In o IIP2 of 114 dBm at 2000MHz addition to providing low insertion loss, the F2914 o IIP3 of 60 dBm at 4000MHz also delivers excellent linearity and isolation High Operating Power Handling: performance while providing a 50 termination to o 33 dBm CW on selected RF port the unused RF input ports. The F2914 also includes a patent pending constant impedance (K ) feature. Z o 27 dBm on terminated ports KZ improves system hot switching ruggedness, Single 2.7V to 5.5V supply voltage minimizes LO pulling in VCOs, and reduces phase External Negative Supply Option and amplitude variations in distribution networks. It 3.3V and 1.8V compatible control logic is also ideal for dynamic switching / selection Operating temperature -40C to +105C between two or more amplifiers while avoiding 4 4 mm 24-pin QFN package damage to upstream /downstream sensitive devices such as PAs and ADCs. Pin compatible with competitors The F2914 uses a single positive supply voltage Competitive Advantage supporting three logic control pins using either 3.3V The F2914 provides constant impedance in all RF or 1.8V control logic. Connecting a negative voltage ports during transitions improving a systems hot- to pin 20 disables the internal negative voltage switching ruggedness. The device also supports generator and becomes the negative supply. high power handling, and high isolation particularly Functional Block Diagram important for DPD receiver use.
