The HMC165S14 is a low-cost GaAS MMIC SP4T switch from Hittite. It is suitable for antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. The switch supports DC-2.0GHz frequency range, has a maximum input power of 22dBm, and a typical insertion loss of 0.3dB. The typical switching time is 25ns.
The HMC165S14 is a low-insertion loss SP4T (Single Pole Four Throw) switch designed for use in antenna diversity, switched filter banks, and general channel multiplexing applications. It operates up to 2.5 GHz but is specifically suited for 800-1000 MHz basestation applications. The device features an integrated 2:4 decoder that requires only two control lines and a negative bias to select each RF path, replacing the four to eight control lines normally required by standard GaAs SP4T switches.
