摘要

硅MMIC功率放大器在830mhz时提供超过1w的输出功率。当偏置在AB类时，该放大器提供30db功率增益，30%功率附加效率(PAE)和50db动态增益控制范围。该放大器使用片上螺旋电感器提供级间阻抗匹配，并在一级中集成负阻抗消除以提高增益和阻抗水平。温度补偿偏置提供了每个放大器级的静态电流的精确控制。

A 1 W 830 MHz monolithic BiCMOS power amplifier

A silicon MMIC power amplifier delivers over 1 W of output power at 830 MHz. When biased in class AB, this amplifier provides a 30 dB power gain, a 30% power-add-efficiency (PAE), and 50 dB dynamic gain-control range. This amplifier uses on-chip spiral inductors to provide interstage impedance matching, and incorporates negative impedance cancellation in one stage to boost gain and impedance level. Temperature-compensated biasing provides accurate control of the quiescent current in each amplifier stage.
