This Relay Kit is suitable for switching RF from DC to 3GHz, and has a low loss and better than 17dB return loss to 2.4GHz. The Axicom HF353 Relay is specified for up to 50 Watts continuous RF power @ 2.5GHz, so should easily handle up to 100 Watts PEP at 70cm, and maybe 50 Watts PEP at 1.2GHz.  We have tested this product with 50 Watts on the 70cm band,. and 20 Watts on the 23cm bands, and found no evidence of heating due to losses.  We cannot however guarantee reliability when using this relay at higher power levels over time, and suggest that it is not hot RF switched to avoid damage.  The tests on this product can be found of the EME225 Kit webpage. 

The Relay coil voltage is 5vdc and a 270ohm resistor can be used on the PC board for 12vdc operation. 

The Product image shows a fully constructed Kit product.  Please refer to the Options Tab for the descriptions of the various products available.

EME225 KIT is a Basic Kit that includes the PC board, HF353 Relay 5v, 3 x SMA connectors, and minor on board components. 

Requires complete construction and soldering of SMD components.  For medium experienced constructors.
