The present invention provides a high frequency power amplifier of an open-loop type, which outputs a signal having a level corresponding to an output level required under control of a power supply voltage for each output power FET, based on a control signal for the output level. The high frequency power amplifier is provided with a bias voltage generating circuit which generates a gate bias voltage of each output power FET according to an output voltage of a power control circuit for controlling the power supply voltage for the output power FET, based on the control signal for the output level.

High frequency power amplifier and wireless communication module

A mass-production transfer support system has a mass-production transfer source managing computer for managing information generated in a trial-production process of a semiconductor device and a mass-production transfer destination managing computer for managing a mass-production process of the semiconductor device. The mass-production transfer source managing computer comprises: quality/recipe information input accepting means; quality/recipe information sending means; apparatus-difference correction information input accepting means for accepting an input of apparatus-difference correction information for correcting a difference in the quality of the semiconductor device associated with an apparatus-difference between semiconductor manufacturing apparatuses; apparatus-difference correction information storing means; and apparatus-difference correction information providing means for storing the apparatus-difference correction information in a database accessible by the mass-production transfer destination managing computer.
