High Isolation Ultimate 1500W Relay Switch 1-500MHz
Wideband Ultimate 1500W Relay Switch 1-500MHz with very low insertion loss, could be used on any frequency from 1MHz to 500 MHz. Extreme high isolation of more than 75dB will protect any sensitive preamplifier including MGF1302 or ATF54143 GaAs FETs or pHEMTs.
This Ultimate 1500W Relay Switch up to 500MHz will outperform CX-520D, CX-600N, and CZX-3500 by power handling, isolation, and current draw. Just 12V 100mA is good enough.
Use this relay for any purpose including HF/VHF Contesting, EME, MS, or DXing to protect sensitive preamplifiers with extremely good power handling.
