EME144 Relay Kit
This Relay Kit is suitable for switching RF from DC to 3.4GHz, and has a low loss and high 50ohm return loss. The Omron G6Z-1F-A-DC12 Relay is specified for up to 10Watts @ 900MHz, but has been used to reliably switch up to 20Watts FM on 1.2GHz.
We have tested these relays up to 50 Watts FM on both the 2M 144MHz and 70cm 430MHz bands. We were not able to detect any rise in temperature which would be RF loss when operated over long periods in time. These as with all relays should not be hot switched which would reduce the life of the relay contacts.
The Kit is quite straightforward to construct so no notes are supplied. Care should be taken to make sure that the relay is accurately aligned on the board before soldering it into place. The SMA connectors need to be soldered on both sides of the board for the bests grounding and return loss.
