HMC222C12 is a broadband non-reflective SP4T switch from Hittite company, with DC to 6GHz frequency range, single positive bias and integrated 2:4 TTL decoder, in ceramic SMT package.
The HMC222C12 is a single positive supply, non-reflective SP4T (Single Pole Four Throw) switch designed for RF telecom and datacom applications covering frequencies from DC to 6.0 GHz. It features true TTL/CMOS compatibility and includes an integrated 2:4 decoder that requires only two control lines and a +5V bias voltage to select the active path.
The document provides guaranteed performance parameters such as insertion loss, isolation, return loss, and input power for compression across the frequency range. It also details absolute maximum ratings, switching characteristics including rise/fall times, functional diagrams, truth tables, package outline drawings, and evaluation board layout information.
