The HMC197 is a low-cost SPDT switch in a 6lead SOT26 plastic package for use in general switching applications which require very low insertion loss and very small size. The device can control signals from DC to 3.0 GHz and is especially suited for 900 MHz, 1.8-2.2GHz, and 2.4GHz ISM applications with less than 1dB loss. The design provides exceptional insertion loss performance, ideal for filter and receiver switching. RF1 or RF2 is a reflective short when "Off". The two control voltages require a minimal amount of DC current and offer compatibility with most CMOS & TTL logic families. The HMC197 is especially suited for PCMCIA wireless card and cellular phone applications. See HMC221 for same performance in an alternate SOT26 pin-out.
