Electronics Research Inc. will show a new family of precision directional couplers at the NAB Show.
The coaxial directional couplers are available for 1-5/8, 3-1/18, 4-1/16 and 6-1/8-inch coaxial transmission lines with one, two, three or four sampling ports. The standard sampling port connections are Type N or SMA.
The line sections are constructed to position and hold the inner conductor securely to ensure the coupler remains stable and calibrated through shipment and installation.
“These directional couplers are constructed with rugged aluminum outer conductors and are very compact, allowing them to be mounted in congested locations,” ERI wrote.
The directional couplers have an operating frequency range from 54 MHz to 800 MHz and can be set for coupling levels from –30 dB to –70 dB with directivity of 30 dB or better.
ERI also makes adjustable coaxial directional couplers and produces waveguide directional couplers for all line sizes used for terrestrial broadcast applications.
