Design of Power Amplifier of Rail Transit Wireless Communication System Based on ADS
Publication: Resilience and Sustainable Transportation Systems
ABSTRACT
The wireless communication system of rail transit has many functions, which plays a very important role in train operation. In order to improve the output power of wireless communication system of rail transit, this paper implemented the design and simulation of power amplifier based on advanced design system (ADS) by using Freescale Semiconductor's amplifier chip MW6S004. The transistor is laterally diffused metal oxide semiconductor. The key to design the power amplifier lies in the matching network, which can find out the best external load impedance ZL at the maximum output power of the power amplifier by using the principle of load-pull. The results show output power>24 dBm, power gain>18 dB, power out at 1 dB compression point>20 dBm in the 1.80 GHz to 2.00 GHz frequency range by experimental simulation.
