The HMC172QS24 is a low-cost SP6T switch for use in antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. The switch can control signals up to 2.5 GHz and is especially suited for 800-1000 MHz and 1700-2000 MHz basestation applications.
The HMC172QS24 is a low-cost SP6T (Single Pole, Six Throw) RF switch manufactured by Hittite Microwave Corporation in a 24-lead QSOP package. It is designed for use in antenna diversity systems, switched filter banks, gain/attenuation selection, and general channel multiplexing applications.
The device operates from DC to 2.5 GHz and features an integrated 3:6 decoder that reduces the required control lines from twelve (typical for GaAs SP6T switches) down to just three control lines plus a negative bias voltage. The switch outputs are reflective shorts when in the off state, ensuring high isolation between paths.
