| Abstract(in English) | Tri-band GaAs FET power amplifiers with a single transistor using lumped element matching circuits are designed and fabricated. The dual-band GaAs FET power amplifier[12-14] is applied to the tri-band power amplifier configuration by using PIN diode switching. The matching circuits are designed using the Chebyshev low-pass type impedance transformer design method. We investigated the tri-band GaAs FET power amplifiers with a PIN diode and two PIN diodes configurations. Their superior performance is confirmed by experimental study of tri-band GaAs FET power amplifiers, and it is believed that this circuit configuration method is useful technique for downsizing and high performance of multiband amplifiers. |
