DUPLEXER FOR SIDE-LOOKING RADAR.
Abstract
The purpose of this program is to advance the state of the art in the field of microwave duplexers intended for application in a sidelooking radar. A three-cavity limiter was designed in which the middle resonator is a single crystal YIG sphere. This unit has been tested at low power and has met the insertion loss and bandwidth requirements. A three-port circulator has been designed. Six ferrite compositions were tested for peak power handling capability. Substantial improvements have been obtained by utilizing a 'hot pressing' technique in the preparation of the magnesium, manganese ferrite body. Data obtained, so far, show satisfactory power handling capability of one composition in excess of 200 kw peak with a .001 duty cycle. A fourport differential phase shift circulator model has been designed and constructed. Several ferrite compositions have been tested at low power level. (Author)
