Title: Distributed microwave amplifier
Inventor: ISHII KYOICHI
IPC: H03F3/193
Filed: 1989-12-28
Abstract: PURPOSE:To increase power gain and output power by reflecting other microwave signal sent through two branched output transmission lines in high frequency ground and synthesizing the reflecting wave signals into one microwave signal of two branched signals with phase synchronization. CONSTITUTION:A 1st stage side of an output transmission line 2 is connected to ground in terms of high frequencies through a decoupling capacitor CD1 and a termination resistor RD whose resistance is 0ohm. Then the inductance of plural inductance elements L1-L6, L11-L15, L21-L26 connected in series with input output transmission lines 1, 2 is specified so that other amplified microwave signal propagated in two branches at each multi-stage connecting point of GaAs MISFETs T1-T5 keeps the synchronization relation with one amplified microwave signal being one of two branched reflection signals reflected at a high frequency ground point. Thus, the reflecting wave signal is phase- synchronized with one microwave signal being one of two branched reflection wave signals to extract part of the power of the reflecting wave signal thereby enhancing the power gain and the output power.
