The F2923 from Renesas is a SPDT absorptive RF Switch that operates from 400 MHz to 8 GHz. This switch utilizes Renesas Kz innovative design technology to maintain a near-constant impedance during transition and minimizes LO pulling in VCOs and reduces phase and amplitude variations in distribution networks. It has a low insertion loss up to 0.48 dB and high isolation of 74 dB. The switch has high linearity with (IIP2) of 116 dBm and IIP3 of 66 dBm. It requires a single positive supply from 1.8 V to 3.3 V and is available in 20-pin TQFN package that measures 4 x 4 mm. It is ideal for dynamic switching/selection between two or more amplifiers while avoiding damage to upstream/downstream sensitive devices such as PAs and ADCs.
