The report describes the SFD-315 magnetron and the Solid State Duplexer and presents the results of various tests conducted to appraise their performance. The ASDE-2 at NAFEC was equipped with specially modified modulators for tests of the SFD-315 magnetron. The Solid State Duplexer was operated at an unmodified channel of the radar and performed satisfactorily throughout a life-test period of 2500 hours. It was concluded that satisfactory system performance can not be achieved using the modified modulators provided for operation of the SFD-315 magnetron however, the SFD-315 magnetron is suitable for ASDE-2 applications with a compatible modulator, and may be expected to operate satisfactorily for more than 5000 hours. It was also concluded that the Solid State Duplexer is a suitable replacement for the original duplexer of ASDE-2. It was recommended that the SFD-315 magnetron not be adopted as a direct replacement for existing ASDE-2 magnetrons but that the Solid State Duplexer be adopted by the FAA as a replacement duplexer for operational ASDE-2 equipments. It was further recommended that procurement specifications for future K-band ASDE radars provide for application of the SFD- 315 magnetron or equivalent ICEM type, incorporation of a compatible modulator and a Solid State Duplexer.
