HALF SIZE CRYSTAL CAN
RADIO FREQUENCY RELAY
75 WATT
Product Description
Series
RFK
This series of coaxial terminated hermetically sealed relays have been designed to provide reliable switching functions in the most
demanding radio frequency applications. The use of 2K relays in the basic construction, has been coupled with a unique and improved
termination network to insure faultless performance under severe environmental conditions.
The design concepts employed in each of this series have been time tested through thousands of hours testing and millions of field
operations to provide the highest degree of reliability.
The following construction features ensure the highest reliability in extreme environments:
-
All welded relay construction
-
Cleaning and sealing techniques ensures maximum internal cleanliness
-
Low level to 2 amperes auxiliary switching
-
1 or 2 form C, RF contacts, special metal alloy with gold plating
-
Frame, armature designs and force / mass ratio provides exceptional shock and vibration immunity
-
Coax interconnections
-
200 watt RF carry capability
-
75 watt RF switching capability
-
Terminated with 6 inches length RG 196A/u Teflon cable.
