General Description
The HMC221 and HMC221E are low-cost SPDT switches in a 6-lead SOT26 plastic package for use in general switching applications which require very low insertion loss and very small size. These devices can control signals from DC to 3 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.The HMC221E is a RoHScompliant product.
