• ADRF5019 Insertion loss is reduced When I repeat switching test

    Hi, 

    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…

  • 关于开关芯片ADRF5019对信号相位变化的影响是否一致?

    想请问一下,单刀双支开关芯片ADRF5019如果RF1与RF2两个引脚输入的是一对共模信号,那么经过RFC输出后的两组信号的相位是否还是一致的?大致的偏差在多少范围以内?

    关于相位变化的信息官网的技术资料里面并没有给出,因此想问一下各位大佬,谢谢了

  • FAQ: Operating SOI Switches with a Single Supply

    Q.

    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)?

     

    A.

    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…

    Hi,

    You can refer to the evaluation board designs for component recommendations and application circuits for design reference.
    For the newer parts, we now post gerber files and more detailed application notes (for example, please refer to the datasheets…

  • 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.
