Precision Directional Couplers

Precision Directional Couplers 

Electronics Research, Inc. offers a complete line of precision directional
couplers for FM radio and VHF and UHF television applications. These fixed
directional couplers are available for 1-5/8-inch, 3-1/8-inch, 4-1/16-inch, and
6-1/8-inch (50 ohm) transmission lines and can be purchased with one (1)
to four (4) coupling probes; they include the required external terminating
loads. These new precision directional couplers are balanced high precision
test instruments. They may be used with ERI’s PWR-100D Power Monitor and
its companion VPS-100 VSWR Monitoring and Protection system, produced in
partnership with Broadcast Devices, or they can be used as a stand alone test
port or even in simple applications such as providing a modulation monitor
sample.
Features
• Balanced directional coupler designed for stand alone test port
applications or for use with ERI’s Monitoring and Protection System.
• Available for 1-5/8, 3-1/8, 4-1/16, and 6-1/8-inch (50 ohm) transmission line
sizes
• Models available with one (1) to four (4) coupling probes
• Includes coupling probe termination load.
