HMC544E

v00.0206 Typical Applications The HMC544 / HMC544E is ideal for: Cellular/PCS/3G Infrastructure Basestations & Repeaters WLAN, WiMAX and WiBro Microwave and Fixed Wireless Radios 10 Functional Diagram HMC544 / 544E GaAs MMIC T/R SWITCH, DC - 4 GHz Features Very Low Insertion Loss: 0.2 dB @ 1.0 GHz High Input P1dB: +39 dBm High Input IP3: +55 dBm Positive Control: 0/+3V to 0/+5V Compact SOT26 SMT Package General Description The HMC544 & HMC544E are low cost SPDT switches in 6-lead SOT26 packages for use in transmitreceive 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 +55 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. SWITCHES - SMT 10 - 300 Electrical Specifications, TA = +25° C, Vctl = 0/+3 Vdc, 50 Ohm System Parameter Frequency Min.
