• ADRF5045 DC coupled

    Dear Analog,

    i'm using ADRF5045 for a tunable filter bank prototype.

    in the datasheet i have seen that every output of the SP4T is DC coupled.

    is it dc coupled to 0V?

    i need to connect a diode varactor at  the ouput of every channel (SP4T) and for…

  • ADRF5045 Raise and Fall time

    Hi, 

    Do you have any information with regards to rise and fall time? 

    The mask Margin is very less when check on Evaluation board .

    Thanking you 

    With best regards and wishes 

  • Bias sequencing question about ADRF5045-evalz

    Hello, I have a question about bias sequencing problem of ADRF5045.

    From the data sheet, ADRF5045 bias sequencing follows 1. GND, 2. VDD, 3. VSS, 4. control voltage before the input.

    And i simply followed the sequencing, but the components keep dying…

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

    Hi BrendanT,

    I see you have DC blocking caps on the RF lines connecting this block to the previous and next block.
    The RF ports are DC coupled to 0V and these connect to the drain/source of the RF transistors. As long as your control signals are clean…

  • 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.
