Product Description
The Broadband Feed Horn 8-18 GHz with Linear Polarization is designed for RF applications requiring wide frequency coverage within the microwave spectrum. It operates across the 8-18 GHz frequency range, uses linear polarization, provides 9.25-11.3 dB gain, and has a specified VSWR of no more than 2.1.
The feed horn is intended for RF monitoring, radio-frequency surveillance, measurements, and testing. Its wide operating bandwidth allows one device to cover a substantial frequency interval, while its compact mechanical dimensions make it convenient for integration into measurement and monitoring systems.
The radiation pattern is specified for both principal planes. The beamwidth varies from 71° to 52° in the horizontal plane and from 71° to 52° in the vertical plane. At an angle of 60° relative to the main lobe, the specified gain level is -10 / -13.5 dB.
The mechanical dimensions are 146.80 mm in overall length and 117.10 mm in front diameter. According to the provided product information, the feed horn is also capable of operating with relatively high power levels; however, an exact numerical power rating is not specified.
