HMC1055LP2CE V00.0912 Typical Applications Features The HMC1055LP2CE is ideal for: Failsafe Operation - “On” When Unpowered • RFID & Electronic Toll Collection (ETC) Wide Vdd Range: 1.2V to 5V • Tags, Handsets & Portables Very Low On State Current: 200 nA • ISM, WLAN, WiMAX & WiBro Low Insertion Loss: 0.7 dB • Automotive Telematics High IP3: +52 dBm • Test Equipment Compact SOT26 SMT Package General Description Switches - SPST - SMT Functional Diagram The HMC1055LP2CE is low-cost SPST Failsafe switch in 2x2mm,8 lead DFN plastic package for use in switching application which require low insertion loss and very low current consumption. With 0.7 dB typical loss, these devices can control signals from DC to 4 GHz and are especially suited for IF and RF applications including RFID, ISM, automotive and battery powered tags and portables. RF1 and is reflective open while RF2 is terminated in 50 OHMs 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.
