High frequency power amplifier for portable communication equipment

The amplifier includes a battery (3) and an IN/OUT stage (4). The amplification stage (1) uses three transistors (5-7) for respective, successive sections. Each transistor has an earthed emitter. A setting stage (2) is equipped with two transistors (14,15) and a constant voltage unit (16). The base...

Summary:The amplifier includes a battery (3) and an IN/OUT stage (4). The amplification stage (1) uses three transistors (5-7) for respective, successive sections. Each transistor has an earthed emitter. A setting stage (2) is equipped with two transistors (14,15) and a constant voltage unit (16). The base of the first transistor (5) is connected through a capacitor (8(1)) and a resistance (8(2)) to a signal input terminal (9), and the collector of the third transistor is connected through the capacitor (10(1)) and the resistance (10(2)) to the signal output terminal (11).
