  • Patent number: 6259901
    Abstract: A radio-frequency power amplifier of mobile communication equipment includes a differential amplifier arranged to balanced-input and amplify a radio-frequency signal delivered from a frequency converter of a transmission system of the mobile communication equipment located downstream of a modulator of the transmission system. The radio-frequency signal delivered from the differential amplifier is further amplified and balanced-output by a push-pull circuit. The differential amplifier and the push-pull circuit are respectively supplied with bias currents varying in dependence on a gain control signal, whereby respective amplification gains of the differential amplifier and the push-pull circuit are variably adjusted.

  • Patent number: 6242985
    Abstract: A semiconductor device for high-frequency power amplification includes a pair of first and second composite transistors each comprised of parallel-connected transistor cells each having parallel-connected transistor elements. The number of the transistor cells is selected to satisfy a requirement on the power capacity of the device. The two composite transistors form a power amplifier circuit for balanced-inputting and performing power amplification of a high-frequency signal. The transistor cells of the composite transistors are alternately formed on a semiconductor substrate on which electrode wiring patterns extending in the transistor-cell arraying direction are formed. Respective electrodes of transistor elements are collectively connected, composite-transistor by composite-transistor, to these patterns.
