资 源 简 介

This application note demonstrates the feasibility of acomplete RF amplifier using Motorola LDMOS transistors inClass AB. The complete design requires standard piece partsand components only yet exhibits superior performance interms of gain, efficiency, power and ruggedness in a GSM 900MHz base station environment.POLYCLAD, er = 4.0), and the PCB is screwed on the baseplate using standard 2.5 mm screws. SMD 0805 componentsare used, and the “ACCUP” series from AVX are used for “highQ” capacitors. All metalized holes in the PCB have a 0.5 mmdiameter, including the hole area used for the grounding andthe cooling of the driver.
