a question
I ordered Today the filters
To repair the RXTX board
of my CMU200
SAW 836.5MHZ
SAW 1842.5MHZ

[100pcs] B39182-B4139-U410 1842.5MHz SAW Filter 50 Ohm SMD

[50pcs] B69813-N1847-X475 PCN RX Filter 1842MHz SMD

[50pcs] B39841-B4122-U410 836MHz SAW Filter SMD

Since the filters I ordered are small size
3 mm x 3 mm
I am considering soldering them on a PCB adapter.

the question
Will the adapter have an effect on the impedance of the filter
????????.???.??????.?????

Most likely it will have an effect because the traces on your radiotest-set i matched lines.

Thanks, that's what I thought too
i will stitch the filter directly to the PCB.
I  sailors
Small copper wires to the pads of the filter
Then solder them directly to the PCB
This is going to be a bit of a headache
With such a small filter
The original was huge
