引言对于用于CDMA2000与W-CDMA基站的大功率放大器(HPA)的设计师来说,他们面临许多完成精确发射功率测量的挑战。其中涉及到的复杂因素包括高的峰均比以及峰均比随基站通话载荷、大的工作温度范围和大的发射功率范围变化而变化。制造商利用精确的有效值(RMS)输出功率测量减小他
Introduction Designers facing high-power amplifiers (HPAs) for CDMA2000 and W-CDMA base stations face many challenges in performing accurate transmit power measurements. The complexities involved include high peak-to-average ratio and peak-to-peak ratio as the base station talk load, large operating temperature range, and large transmit power range change. The manufacturer reduces the output power with accurate RMS measurements
