HMC349LP4C / 349LP4CE v02.1205 HIGH ISOLATION SPDT NON-REFLECTIVE SWITCH, DC - 4.0 GHz Typical Applications The HMC349LP4C / HMC349LP4CE is ideal for: * Basestation Infrastructure * MMDS & 3.5 GHz WLL * CATV/CMTS Features High Isolation: 67 dB @ 1 GHz 62 dB @ 2 GHz Single Positive Control: 0/+5V +52 dBm Input IP3 Non-Reflective Design All Off State 8 SWITCHES - SMT * Test Instrumentation Functional Diagram 16 mm2 Leadless QFN SMT Package General Description The HMC349LP4C & HMC349LP4CE are high isolation non-reflective DC to 4 GHz GaAs MESFET SPDT switches in low cost leadless surface mount packages. The switch is ideal for cellular/PCS/ 3G basestation applications yielding 60 to 65 dB isolation, low 0.9 dB insertion loss and +52 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. On-chip 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 put the switch in an "all off" state.
