I am using HMC703 in a design and I have two questions:
Q1: In the evaluation board schematics, there are several 1 ohm resistors on power supply pins between decoupling capacitors. Are these resistors really necessary? (I have already ferrite beads between HMC860 LDO and HMC703)
Q2: There are four 4.7uF capacitors around THS4031CD (loop filter Opamp) in parallel with 100nF capacitors. Isn't that too big? Isn't it better to put 10pF parallel with 100nF?
