The Challenge: Design a high efficiency power amplifier is very difficult to succeed in an one time design in high frequency microwave circuit in current 4thgeneration communication system. To do it by using design software such as AWR, we can simplify the circuit and system design including behaviour and measured model of each component such as transistor, capacitor, resistance and inductor. So we can minimize significantly a development time of power amplifier (PA). After fabrication a printed circuit board, we have to measure the fabricated circuits but we need many sophisticated equipment’s to measure the performance of PA. To measure a 4th generation communication system we need a lot of equipment. In traditional test equipment, these are controlled by GPIB to communicate with each equipment but the speed of GPIB, is very slow so it is limited measurement speed. Compared to this traditional measurement system, the PXie bus system of NI platform is very fast. So it is very advantage especially in industry to speed up the measurement to fabricate the product in a limited time comparing to the competitor. So by using Labview, we can customize the test scenario to speed up the test and also we can easily transform the used NI equipment for the other test set up in NI chassis structure with Labview programming. So in this project, we propose an one-time success design methodology to design a difficult high power amplifier system and demonstrate a measuring method by using NI platform.
The Solution: We use NI MIMO platform such as 4x4 MIMO systems that are vector signal generators, vector signal analyzer, power meter and vector network analyser including power supply in PXIe environment. Also we use famous and proven software AWR form NI to design a high efficiency power amplifier with LTE 4th generation signal.
