HMC349ALP4CETR

RF 开关 IC DC-4 GHZ Hi Isolation Switch

High Isolation SPDT  Non-Reflective Switch, DC - 4 GHz

Typical Applications

The HMC349ALP4CE is ideal for:

• Basestation Infrastructure

• MMDS & 3.5 GHz WLL

• CATV/CMTS

• Test Instrumentation

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 put the switch in an “all off” state.
