Application Note AN098 (Layout Review Techniques for Low Power RF Designs) recommends using a 0-ohm resistors in series for un-mounted components in a pi filter for antenna matching.
Some 0-ohm resistors have a very poor frequency response. My design operates on the 433 MHz UHF band. What resistor/jumper technology would be the best for this type of jumper? I'm considering solid copper strips and metal based sensing resistors (at around 1-5 miliohm).
We have never seen this as an issue. A 0 ohm resistor contribute about 0.3 nH. We use resistors from Vishay at the moment.
In other words I don't see any reason for using something different from a 0 ohm resistor.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
