This paper presents the performance, design and fabrication of the target output circuit for a 4‐GHz deflection‐modulated EBS amplifier.
mounted, have beenn obtained. The relationship between the circuit and output performance is analysed; an output circuit for miniaturization and wide ‐ band operation has been designed. A 4 ‐GHz EBS amplifier has been fabricated and its output investigated. Results show that the output circuit for series parallesl type and has wider bandwidth. The 4 ‐GHz EBS amplifier, using microstrip line output and series diode type circuit ,gives a maximum output of 4.7 Wat 4.25 GHZ, a ‐3 dB bandwidth of 300 MHZ and a gain of 16.7 dB ;these experimental values agree well with the analytical results.
