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