Özet

In this paper, a wideband driver amplifier (DA) with flat gain is presented for driver stage in high power amplifier. The presented driver amplifier consists of 11 dB gain block, positive slope equalizer and power amplifier stage with 24 dB small signal gain. The designed DA has 500 mW (27 dBm) output power and operates along 2-6 GHz frequency band. This DA is designed to be implemented on the Rogers RT5870 dielectric substrate. MiniCircuit Lee29+ transistor and GaN based Qorvo TGA2597 transistor are used in the design. The performance of the designed DA was evaluated by making small signal simulations. The DA offers a small signal gain of 35 dB over the frequency band of 2-6 GHz.
