HMC544A / 544AE v00.1212 GaAs MMIC T/R SWITCH, DC - 4 GHz Typical Applications Features The HMC544A / 544AE 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: +60 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 The HMC544A & HMC544AE 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 control signals from DC to 4.0 GHz and are especially suited for 450, 900, 1900, 2300, and 2700 MHz applications with <0.5 dB insertion loss. This GaAs PHEMT design provides exceptional linearity performance of +36 dBm 1dB compression point and +60 dBm third order intercept at +3 volt bias. RF1 and RF2 are reflective opens when Off. On-chip circuitry allows positive control operation at very low DC current. Electrical Specifications, T = +25 C, Vctl = 0/+3 Vdc, 50 Ohm System A Parameter Frequency Min. Typ. Max.
