• Low frequency operation of HMC8038

    It is mentioned in the manual of HMC8038 that it should be operated at a frequency greater than 100MHz. I have a series of applications. The operating frequency may be 40MHz, 80MHz or 160MHz. We plan to use HMC8038, but I am worried about its performance…

  • HMC8038 isolation between two output ports


    I would like to use the isolation path between RFC1 and RFC2 of HMC83038 switch as a back calibration path for my signal. I see in S2p parameters provided that there is around 60dB isolation loss at 940 MHz, that works for my application (880-980…

  • HMC8038 Isolation Problem ?

    I observed a problem about the SW HMC8038. When I measure the IL from RF1 to RFC (RF2 terminated with 50 ohm), I measure 1 dB for VCTL = 1 and  41 dB for VCTL = 0 at 1.5 GHz. That means the isolation is about 40 dB but should be higher. 
  • Can HMC8038 used in WiFi 6E band 5925MHz~7125MHz? or do we have linearity data such as P0.1dB or IIP3 up to 7.125GHz?


    One of our customer want to use HMC8038 in WiFi 6E band 5925MHz~7125MHz.

    HMC8038 data sheet gives some data about insertion loss up to 7GHz.

    And according to the S parameter that provided on our official website, the insertion loss, return loss and…

  • Power supply requirements for VDD and Control Voltage for HMC8038


    We are using the HMC8038 RF Switch Evaluation board in a concept to switch between TX/RX to Antenna.

    For Supply and Control voltages to the HMC8038, we are tapping off the +5V supply from HMC981 Bias controller for a HMC8410 LNA device.

    What are the…

  • HMC8038

    With reference to the above mentioned part.Please let me know,whether the RFC and RF1,RF2 pins can withstand a voltage of 24V?

  • HMC8038 Power Up Sequencing

    For HMC8038 normal operation, power up sequencing need to be followed as per datasheet?

    Ideal power-up sequence is mentioned on page no. 9.

  • RE: Request additional spec. of HMC8038 related ATE

    This question has been closed by the EZ team and is assumed answered.
  • HMC349ALP4CE and HMC8038

    I reviewed the specifications for HMC349ALP4CE and HMC8038. I understand that HMC8038 is newer.
    We would like to use one of these switches at 10MHz. The signal is not a pure sine tone, but is closer to the square way.
    Thus, the subharmonics will extend…

  • RE: what is rise time and fall time of HMC849ALP4CE and HMC8038?

    Hi Sinan.Onat,

    The typical rise and fall time for the HMC8038 is ~35-40ns.

    The typical rise time for the HMC849A is ~60ns

    Please note, there will be some part-to-part, and process variations. The GaAs process (HMC849A) will have more process variations…
