How can i use HMC349ALP4CE in DC mode.I would like to use HMC349ALP4CE SPDT SWITCH in DC-500MHz frequancy .so can you please mention is there i need to change the circuit.

Thanks in advance.

  • Hi saigupta,

    What is the power level you are looking to operate at?
    The HMC349ALP4CE can be used at 10kHz with degraded power handling and linearity.

    Instead, I would recommend the newer pin-compatible silicon alternative, HMC8038. The HMC8038 also has degraded power handling and linearity performance at 10kHz, however, the performance holds better than the HMC349A at lower frequencies. Please see attached.
