Summary:
A design of the unilateral microwave transistor amplifier in the conjugately characteristic impedance transmission line (CCITL) system the T-chart is reported. It is observed that the unilateral property of the transistor is maintained after integrating to the CCITL system. The variations of the gain factors calculated using the characteristic conductance approach (CC) with the argument φ that is the argument of the line characteristic impedance are compensated for one another resulting in the constant unilateral transducer power gain GTU. Series single-stub tuning is employed for circuit matching. It is observed from numerical results that stub lengths for both input and output matching networks decrease with the argument φ but the variations of the distance between the stub and port for both networks are different. These results indicate that a better design may be achieved by selecting the proper argument φ.
