摘要

功率放大器模块构成无线收发器在发射模式期间的最大电流损耗。在未来用于数字无线收发器的蜂窝网络中，基站将自适应地调节每个收发器的传输p / w电平，以使尽可能多的用户共享一个无线信道。这就需要一个具有宽范围数字可选输出电平的高效率功率放大器。这里报告的功率放大器是用于在902- 928mhz频段工作的全cmos跳频扩频收发器。它提供的可控功率在20pw和20pw之间。从3v电源到天线。

A 900 Mhz Cmos Rf Power Amplifier With Programmable Output

The power amplifier module constitutes the largest current drain on a wireless transceiver during transmit mode. In future cellular networks for digital wireless transceivers, the base station will adaptively regulate the transmitted p o i w leeels of each transceiver to enable the largest possible number ofusers to share a wireless channel. This requires a high-efficiency power amplifier with a digitally selectable output level spanning a wide range. The power amplifier reported here is intended for use in an all-CMOS frequency-hopped spreadspectrum transceiver operating in the 902-928 MHz band. It delivers a controllable power between 20-pW and 20. " from a 3-V supply to the antenna.
