• ADRF5020 Video switching Noise

    Please can someone indicate if this switch has similar low Video breakthrough noise compared to the HMC547 as this is a silicon process instead of a the 547's GaAs MESFET process.

     

     I am using this in a 2-18GHz application and need to know if i need…

  • HMC547A

    Hello,

    Could you please tell me if the HMC547 can be used as follows:

    Can the RF signal be passed through from the RF1 to RF2 pins and the RFC pin left open?

    The control inputs would then be tied together and both driven to the same logic states.…

  • HMC547ALP3E RFC connected to HMC641ALP4E RFC with no AC coupling cap, weird insertion loss behavior

    I have a fan-out circuit suing a HMC547 (to select src or cap) connected via RFC to a HMC641 to mux out to 4 lines

    The board has AC coupling caps on all the RF inputs but the RFCs are connected together DC coupled (oversight)

    I am getting weird issues…

  • RE: HMC494 how to prevent self oscillation in differential mode

    Hi Marty, thanks for your reply.

    Yes all the DC blocking caps are broadband caps.

    1) Regarding oscillation. Yes i am driving differential. There is an RF switch is between the PLL output and the HMC494 divider inputs. The differential signal is not always…

  • Impedance related issue with HMC547LP3E

    Hi,


    I've been evaluating the SPDT HMC547LP3E, DC-20GHz as well as an SP4T HMC641, DC-20 GHz switch for use in one of my projects, using the evaluation modules. However, during my testing I noticed that the impedance of the switches jumps to ~65 Ohms…
