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.
Unfortunately when we did these tests, the files saved the curves in light Green which has made it difficult to read. All tests were done on a modern calibrated Anritsu Network Analyzer. All test cables & connectors were used when calibrating the Analyzer to cancel the influence of these on the readings. The first set of readings are from 500MHz to 1.5GHz & the second set from 1.5GHz to 3.5GHz.
The tests show that the Relay & PC board have got excellent properties for use up to 3.5GHz.
