Design of Ultra-wideband Power Amplifier Module

This paper introduces a design of ultra-wideband power amplifier module, focusing on constant voltage and constant current supply circuit design, bias tee design, broadband PCB transmission line matching design. The supply circuit design and bias tee design are proposed which enhance the power gain and output power. Broadband PCB transmission line matching design can reduce transmission line loss and improve module gain. Design index: The frequency range covers 100kHz∼26.5GHz, transmission gain ≥ 10dB, maximum input power ≥ 8dBm, maximum output power ≥ 20dBm. According to the design proposal, the ultra-wideband power amplifier module is realized. The vector network analyzer is used to test the relevant indexes of the power amplifier module, including frequency range, gain, maximum input power, maximum output power, input return loss, output return loss. The test consequences of the power amplifier module satisfy the design requirements.
