The F2910 from Renesas is a SPST absorptive RF switch that operates from 30 MHz to 8000 MHz. The switch provides an isolation of 51 dB and has an insertion loss of 0.55 dB at 2 GHz. It uses a single positive supply voltage supporting either 3.3 V or 1.8 V control logic.
The F2910 uses Renesas's constant impedance K|Z| technology. The K|Z| constant impedance technology provides a major performance improvements in maintaining the desired impedance of the RF terminals of an RF switch while it is being switched. Standard RFs switches exhibit large impedance changes while transitioning between states. This switch is available in a 2 mm x 2 mm, 8-pin VFQFP-N package and is ideal for base station, portable wireless, repeaters and emergency 911 systems.
