Title: High-frequency power amplifier
Inventor: OTSUSAKA OSAMU
IPC: H03G3/30
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To improve the linearity by controlling the bias of a power amplifying element according to the differential amplification signal between an input power detection signal and an output power detection signal. SOLUTION: An inputted high-frequency signal passing through a directional coupler 1 is amplified by AMPCs (power amplifying elements) 2 and 3, and outputted through a directional coupler 4. Progressive waves of input power and output power are extracted as detection signals by the directional couplers 1 and 4, and they are adjusted by VRs (variable attenuator) 5 and 6 so that their detection voltages become the same level. A differential AMP 9 receives the detection signals of the input power and output power and extracts and converts only a distortion component of linearity into a control signal. The control signal controls the bias voltages or currents of the AMPs 2 and 3 composed of FETs through a control circuit 10. Consequently, characteristics such as differential gain and lower-sideband reproduction quantity of a TV broadcasting device are improved.

Filed: 1993-06-23
Abstract: PURPOSE:To obtain a large heat conveying amount and to make the structure in the height direction compact by arranging a switching valve between a receiver and a gas/liquid separator, piping a top of the separator to a first check valve through the receiver and a mesh filter, and opposing the filter in a receiver vessel.
