Overview

Failsafe Operation - “On” When Unpowered
Wide Vdd Range: 12V to 5V
Very Low On State Current: 200 nA

Low Insertion Loss: 0.7 dB
High IP3: +52 dBm
Compact SOT26 SMT Package

The HMC550A and HMC550AE are low-cost SPST Failsafe switches in 6-lead SOT26 plastic packages for use in switching applications which require low insertion loss and very low current consumption. With 0.7 dB typical loss, these devices can control signals from DC to 6 GHz and are especially suited for IF and RF applications including RFID, ISM, automotive and battery powered tags and portables. RF1 and RF2 are reflective opens when “Off”. The switch requires a minimal amount of DC current in the “On” state, and offers compatibility with CMOS and some TTL logic families. The failsafe topology results in the switch being normally “On”, i.e. low insertion loss from RF1 to RF2, when no DC bias is applied.
