High Frequency 0 ohm resistor

[Antenna (^.^)]

Hi everybody,

I am having trouble finding a 0 ohm resistor (SMD) that can handle frequencies
from 0.9GHz to 2.4GHz.

I have looked on mouser, digikey and element 14.
Does anybody have any suggestions?

Thanks!!

At those high frequencies I wouln't even try to use a 0 ohm resistor bridge since its self inductance and capacitance could decompensate the line where the signal is transfered. If I were you and were making the PCB design, I would make the bridge with another signal trace, maybe a IF signal trace or even better, a supply one.

You could try with some 0603 or 0402 resistor, maybe a thin copper wire would help too.

Thanks for your reply!!
Umm could you give an example of what you mean? I am not really understanding it..:???:

At those frequencies you generally need a controlled impedance line on a PCB such as with microstrip or stripline. Zero-ohm (jumper) connections generally won't work well due to the impedance mismatch those would cause.

What is the purpose of this zero-ohm connection?

I think the question is unclear.

Most small SMD parts can "handle" microwave signals up to 2.4 GHz. Pad and package impedances have to be considered, as you need to do for any PCB structure that isn't continuing the designed transmission line impedance.
