Navy Calibration Program Instrument Calibration Procedure GN-04 WAVEGUIDE DIRCTIONAL COUPLES H & X BAND 0 TO 30 DB COUPLING

摘要

This procedure describes the measurement of the coupling coefficient and directivity of waveguide directional couplers which operate in the frequency range of 7.05 through 12.4 Gc (kMc), including the representative types listed in appendix A.nThe commonly used band designations and corresponding waveguide sizes and frequency ranges are specified in table 1. The unit under test will be referred to herein as the Test Instrument.
