| HMC550 / 550E v00.0306 GaAs MMIC SPST FAILSAFE SWITCH, DC - 6 GHz Typical Applications The HMC550 / HMC550E is ideal for: * RFID & Electronic Toll Collection (ETC) * Tags, Handsets & Portables * ISM, WLAN, WiMAX & WiBro Features Failsafe Operation - "On" When Unpowered Positive Control: 0/+2.2V to 0/+5V Very Low On State Current: 200 nA Low Insertion Loss: 0.7 dB High IP3: +52 dBm Compact SOT26 SMT Package 8 SWITCHES - SMT * Automotive Telematics * Test Equipment Functional Diagram General Description The HMC550 and HMC550E 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 6.0 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.
