Test and Evaluation of Broadband VHF Isolator.

Abstract

This report describes a prototype broadband VHF ferrite isolator device that can be used to reduce transmitter intermodulation in air traffic control air/ground communication equipments. The isolator was developed for the Systems Research and Development Service through an Inter-Agency Agreement with the United States Air Force. The isolator was tested at the National Aviation Facilities Experimental Center and was found to reduce T-1108/GRT-21 transmitter intermodulation approximately 30 dB. Test results fell short of design goals for weight, insertion loss, and intermodulation product reduction. (Author)
