Realization of an Amplifier in Slotline Technique

In this paper the readability of a hybrid amplifier using slotline technique is investigated. With the help of a linear circuit simulator and additionally implemented models for the slotline and its short circuit stub a design of the amplifier for a centre frequency of 5.8GHz is carried out. The measurements compared with the simulation show good agreement at the frequency of operation. Discrepancies above this frequency indicate that models for further slotline discontinuities have to be incorporated into the circuit simulator to reflect the measured frequency response
