摘要

为TDMA/CDMA应用开发了一种双射频输入高线性功率放大器，适用于1850至1910 MHz的PCS频段。它具有模具，输入开关，主动偏置传感和调节，50/spl ω /输入匹配和断电控制。需要单个正电源电压。该放大器封装在低成本的塑料超小型SSOP-16封装中。在数字运算中，在800mw和22db增益下，相邻通道抑制功率优于30dbc。最大输出功率2w。典型的大功率附加效率(PAE)为40%。

A low cost linear AlGaAs/GaAs HBT MMIC power amplifier with active bias sensing for PCS applications

A dual RF input high linearity power amplifier for PCS bands from 1850 to 1910 MHz has been developed for TDMA/CDMA applications. It features on die, input switching, active bias sensing and regulation, 50/spl Omega/ input matching and power down control. A single positive supply voltage is required. This amplifier is packaged in a low cost plastic super small SSOP-16 package. In digital operation adjacent channel power rejection is better then 30 dBc at 800 mW and 22 dB of gain. Maximum output power is 2 W. Typical high power added efficiency (PAE) is 40%.
