HMC349ALP4CE

Switches - SPDT - SMT v01.0314 Typical Applications The HMC349ALP4CE is ideal for: Basestation Infrastructure MMDS & 3.5 GHz WLL CATV/CMTS Test Instrumentation Functional Diagram HMC349ALP4CE High Isolation SPDT Non-Reflective Switch, DC - 4 GHz Features High Isolation: 67 dB @ 1 GHz 62 dB @ 2 GHz Single Positive Control: 0/+5V +53 dBm Input IP3 Non-Reflective Design All Off State 16 mm2 Leadless QFN SMT Package General Description The HMC349ALP4CE is a high isolation non-reflective DC to 4 GHz GaAs MESFET SPDT switch in a low cost leadless surface mount package. The switch is ideal for cellular/PCS/3G basestation applications yielding 60 to 65 dB isolation, low 0.9 dB insertion loss and +53 dBm input IP3. Power handling is excellent up through the 3.5 GHz WLL band with the switch offering a P1dB compression point of +31 dBm. Onchip circuitry allows a single positive voltage control of 0/+5 Volts at very low DC currents. An enable input (EN) set to logic high will p...
