• ADRF5019 Insertion loss is reduced When I repeat switching test


    I wonder if there is something wrong with the chip, ADRF5019.

    I used this chip to implement SPDT Switch.

    Now, It is under the test which is related to loss reliability to secure constant Insertion loss value after repeatedly switched.

    Problem is…

  • FAQ: Operating SOI Switches with a Single Supply


    Many of the RF and Microwave SOI switches require dual voltage supplies (VDD and VSS). Which of these may be operated with only a single positive supply (VDD)?



    Certain switches from the SOI portfolio may be operated using only a single positive…

  • ADAR1000 with RF Switch

    When attempting to control the ADRF5019 by driving 3.3V out of the ADAR1000 TR SW POS,  are multiple writes required to register 0x030 and 0x031 because the chip is looking for several repeat commands or because the initial command may not result in output…

  • RE: 36GHz RF oscillation signal source

    You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL),  HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
