EME259 PC Board Description:

The Omron G2RL-1-E-DC12 Relay Kit is suitable for switching RF from DC to at least 350MHz, and has a low loss and better than 15dB return loss to 450MHz. Due to the contact rating of the relay, it should easily handle up to 400 Watts on the VHF, and 1KW on the HF bands. 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 or NC contacts on the bottom of the board.

EME259 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 fully seated into the PC 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
