<p>A power amplifier, especially for mobile radio systems, achieves high efficiency while maintaining stability by frequency translating the input signal during the power amplification process. Two class C amplifiers (q5, q6) have their outputs coupled together and have their inputs driven differentially. The transistors (q5, q6) are biassed for optimum efficiency and to ensure unsaturated class C operation.</p> |
