  • RE: HMC788A damaged

    Dan,

    We're seeing the same issue and we are using a 6.7 uH conical inductors from Piconics. We see the same sort of thing. The current draw shoots up and the amp dies. It still passes a signal through it but there is no amplification.

    It seems to…

  • HMC788A: inductor for single tone @ 5GHz

    Hello,

    I want to use the HMC788A in order to amplify a 5GHz single tone provided by a PLL (LTC6948-3).

    I'd like to avoid using the bulky spiral inductor proposed in the evaluation board.

    Given the frequency, which SMT inductor would you recommend…

  • HMC788A gain

    We designed the Eval board for HMC788A by ourselves, but only got 8dB gain at 8GHz while should be 12+dB at datasheet.  What is the concern for the PCB design? Can let me know the detail design information of the PCB structure?

  • HMC788A-EP Gain Flatness vs. Frequency

    The gain flatness vs frequency of HMC788A-EP (Enhanced Product) looks better than the commercial grade (HMC788ALP2E). Are the two devices not the same but with different qualification.

  • Is there an easy way to reduce the gain of HMC788A?

    HMC788A has too much gain in my LO signal chain and I believe that it is causing excessive dc offsets in my IQ demodulator. Is there an easy to reduce the gain to around 7 or 8 dB? 

  • Question about PCB design of HMC788A and HMC408LP3E

    Hello,

    My customer are considering to use HMC408LP3E and HMC788ALP2E.

    And they have some issues to darw PCB artwork related desiding size of pattern.

    Please refer below questions and let me know your opinions.

  • about HMC788ALP2E

    Hello,

    For HMC788A, it needs a 10nF capacitor at RF input port and RF output port.

    And in datasheet, it shows these capacitors (C1 & C2) are 0502 size package (Table 5 at page 10).

    Due to general package is 0402, so are these two capacitors special…
