NSI-RF-SG10 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – W-Band (WR10) Standard Gain Horn

NSI-RF-SG10
W-Band (WR10) Standard Gain Horn
DESCRIPTION
NSI offers a complete line of Standard Gain Horn (SGH) antennas for gain calibration by the substitution
method. All NSI SGHs are designed and built to meet the requirements of NRL Report 4433 and include
theoretical gain versus frequency curves. Frequency coverage is based on standard “WR” waveguide bands.
CAPABILITIES
See graph below.
THEORY
Gain reference measurements are made by measuring the power of levels of both the antennas under test and
a SGH. The Gain, in decibels, of the AUT can be calculated by using the expression:
GAUT = GSGH Theoretical+ (PAUT measured - PSGH Measured)
Where:
GAUT = Calculated gain of the AUT (in dBi)
GSGHTheoritical = Theoretical gain of the SGH (in dBi)
PAUTMeasured = Measured power of the AUT (in dB)
PSGHMeasured = Measured power of the SGH (in dB)
Care must be taken to match the line and inputs of both the AUT and SGH to obtain accurate results.
