摘要： An antenna of small size is provided which can be mass-produced, which is suitable for use with a portable receiver and which does not require provision of a separate matching circuit. The antenna includes a plurality of meander antennas printed on at least one dielectric film and satisfying respectively different resonance conditions in a frequency band used by the receiver, at least one dielectric solid cylinder for winding the dielectric film therearound, and a dielectric hollow cylinder for covering the dielectric film wound around the dielectric solid cylinder. The individual meander antennas printed on the dielectric film do not make direct electrical contact with each other, and one of the meander antennas connected to a feeder or a helical antenna surrounding the dielectric solid cylinder acts to produce multiple resonance by means of electromagnetic coupling with the other meander antennas, thereby widening the frequency band. The dielectric solid cylinder around which the dielectric film is wound or to which the dielectric film is bonded may be replaced by a dielectric polygonal prism such as a dielectric square prism. In the antenna, impedance matching with the radio frequency part of the receiver can be satisfactorily achieved, so that an antenna of low cost suitable for portable receivers can be offered.

摘要： The RF power amplifier includes first and second amplifiers Q1 and Q2 as final-stage amplification power devices connected in parallel between an input terminal RF_In and an output terminal RF_Out. The amplifiers Q1 and Q2 are formed on one semiconductor chip. The first bias voltage Vg1 of the amplifier Q1 is set to be higher than the second bias voltage Vg2 of the amplifier Q2 so that the amplifier Q1 is operational between Class B and AB, and Q2 is operational in Class C. The first effective device size Wgq1 of the amplifier Q1 is intentionally set to be smaller than the second effective device size Wgq2 of the amplifier Q2 beyond a range of a manufacturing error of the semiconductor chip. An RF power amplifier that exhibits a high power-added efficiency characteristic regardless of whether the output power is High or Low can be materialized.

摘要： For use in an amplifier configuration including a high-power amplifier and a low-power amplifier which are always interconnected in terms of high frequencies and between which switching is made using no switches, a highly stable high-frequency power amplifier module with high isolation between the amplifiers is provided. To reduce wrapping around from a low-power amplifier section in an activated state to a high-power amplifier section in a deactivated state or from the high-power amplifier section in an activated state to the low-power amplifier section in a deactivated state, an input matching circuit having high isolation characteristics is included in an input matching circuit portion which does not have much to do with amplifier efficiency. Switching of each of the amplifier sections between an activated state and a deactivated state is effected by control using bias input terminals.
