6 1/8″, Non-Flanged, 4 ports Directional Couplers

6 1/8″, Non-Flanged, 4 ports

Shively Labs manufactures directional couplers to provide constant monitoring of main-line RF power and to detect RF system problems as they are manifested by reverse power flow (reflected power). A directional coupler output can activate such protection systems as transmitter shutdown or transmitter power reduction, and can display incident and reflected power using an optional reflectometer display unit.

A single directional coupler monitors RF power in one direction only; that is, either incident or reflected power. A dual directional coupler monitors both incident and reflected power. The coupled output is RF, but various detectors can be supplied to convert the RF.

General specifications

  • Frequency: 87.5 – 108 MHz; other values by request
  • Coupling value: –50 to –60 dB; other values by request
  • Directivity: > 30 dB standard; other values by request
  • Typical VSWR: 1.02 : 1
  • Output: RF standard
  • Loads: Included in RF couplers
  • Construction: Aluminum outer with copper inner

These directional couplers are designed so that a spectrum analyzer can be attached directly to them, thus displaying the frequency spectrum and showing any distortions. An optional RF monitoring port is available, to provide a nondirectional, uncalibrated RF signal for less-precise monitoring.

The couplers have the added feature of a building block design which allows both detectors and loads to be removed in the field for purposes of checking the individual parts; i.e. detector, load or basic coupler. Contact the factory for a quotation.
