New REW-14 Coaxial Relay

For High-Power up to 900 MHz !

SPST normally Open

High quality Soviet production. Designed for Power RF applications in the
Space and Aviation devices. The switch provides extremely high reliability,long life and excellent electrical performance characteristics over the frequency range of DC-900 MHz

The REW-14 Coaxial Relays intended for switching the radio-frequency coaxial 50 ohm chains in without current mode to switchings.Perfect for switching the output of PA, connection of any HF-VHF-UHF antenn. Low circuit losses and stable contact resistance, allowing for low thermal and RF noise generation.

Perfect and easyfor converting your HF-UHF amplifier to QSK !

High shock & vibration resistance.

The relay body utilizes copper material with the inner silver conductors sealed into the ends of the housing by ceramic disk insulators. The inner conductors are electrically connected by means of a switch plate slotted for multiple contacts.

Contacts are made from an Silver-Iridium alloy !
