As part of my 20m transceiver build I'm looking for a relay to by-pass an RF amplifier in the front-end board. So, to be clear, that's after the 20m broad bandpass filter and before the RF mixer (it's a single-conversion superhet design).
Being the enterprising individual I am, I would normally scavenge for relays from old scraped radio gear. But, on this occasion I feel the need to invest in a few newly purchased relays to have on-hand. Specialized RF relays can be quite expensive, so I'm wondering if there are specifications to watch out for to help choose a relay from the general herd.
In my case, the coil voltage and contact voltage will be low, say 5 or 6 volts for the coil and a tiny voltage on the contacts. The required current handling capability will also be low. So, these parameters are a given.
However, beyond that I'm wondering what I should be watching out for? For example, my local parts supplier has a class of relays called "Signal Relays", which I assume are aimed primarily at the telco market. Here's one I pulled at random (sort of): https://www.farnell.com/datasheets/1683386.pdf. Are there any aspects or specifications of this particular relay that would make it a bad candidate for HF RF applications? Regards!
