• HMC498LC4 over 20mils Substrate

    I would like to use this amplifier inside new design made over 20 mils RO4350 substrate thickness. Without deembeded S-parameters it is quite hard to make it work well in wider bandwidth. 

    I would apreciate some help on this issue or some shared experience…

  • 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.
