General Description
The HMC221 is a low-cost SPDT switch in a 6-lead 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 - 2.2 GHz, and 2.4 GHz ISM applications with less than 1 dB loss. The design provides exceptional insertion loss performance, ideal for fi lter and receiver switching. RF1 and RF2 are refl ective shorts when “Off”. The two control voltages require a minimal amount of DC current and offer compatibility with most CMOS & TTL logic families. See HMC197 for same performance in an alternate SOT26 pin-out.
