SAC-2507-075-S2

Rev 1.2

Description:
Model SAC-2507-075-S2 is a D-band conical hornantenna that operates from 115 to 140 GHz. Theantenna offers 25 dBi nominal gain and a typical half
power beamwidth of 9 degrees on the E-plane and 10
degrees on the H-plane. The horn also offers typicalsidelobes of -18 dB on the E-plane and -28 dB on the Hplane. The conical horn can support linear and circularpolarization. The input of this antenna is a 0.075” diameter circular waveguide with UG-387/U-M flange.
