HMC544 544E / v00.0206 GaAs MMIC T/R SWITCH, DC - 4 GHz Typical Applications Features The HMC544 / HMC544E is ideal for: Very Low Insertion Loss: 0.2 dB @ 1.0 GHz • Cellular/PCS/3G Infrastructure High Input P1dB: +39 dBm • Basestations & Repeaters High Input IP3: +55 dBm • WLAN, WiMAX and WiBro Positive Control: 0/+3V to 0/+5V • Microwave and Fixed Wireless Radios Compact SOT26 SMT Package Functional Diagram General Description 10 The HMC544 & HMC544E are low cost SPDT swit- ches in 6-lead SOT26 packages for use in transmit- receive applications which require very low insertion loss at medium power levels. These devices can T M control signals from DC to 4.0 GHz and are especially suited for 450, 900, 1900, 2300, and 2700 MHz S applications with <0.5 dB insertion loss. This GaAs - PHEMT design provides exceptional linearity S performance of +36 dBm 1dB compression point and E +55 dBm third order intercept at +3 volt bias. RF1 H and RF2 are refl ective opens when “Off”. On-chip C circuitry allows positive control operation at very low T I DC current.
