EME233 PC Board Description:

This Omron G6S-2F-DC Relay Relay Kit is suitable for switching RF from DC to at least 500MHz, and has a low loss and better than 25dB return loss to 500MHz. Due to the contact rating of the relay, it should easily handle up to 50 Watts on the 450MHz band. The relay is ideal for antenna switching, but the isolation between the contacts should be taken into account when it is used to switch low noise receive pre-amplifiers. Relay isolation can be improved for a particular frequency band, by fitting an SMD inductor across the NO contacts on the bottom of the board.

We have tested this product with 50 Watts on the 70cm band, and found no evidence of heating due to losses.

Kit Constructors Alert:

There are no current alerts.

EME233 KIT Notes:

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. SMA connectors are recommended for the best performance, and need to be soldered on both sides of the board for grounding. Alternatively RG316 coax cable can be used, but good microwave terminations to the board are required. BUY THIS PRODUCT
