摘要

描述了一种完全无源但频率灵活的发射机组合系统，该系统允许每个站点发射机在其频率窗口内移动到任何频率，从而允许在12.5 mhz频率分配内的416个频率中的任何一个瞬间选择。描述了该系统，并将其与可用的替代方案在频率敏捷性、选择性、直流到射频效率、互调抑制、空间利用率和初始成本方面进行了比较。描述了在美国俄勒冈州波特兰的一个非有线系统中的现场测试，并讨论了系统对当前和未来频率规划的适应性。

A new frequency agile transmitter combining system for North American cellular

A totally passive yet frequency-agile transmitter combining system is described, which allows each site transmitter to shift to any of the frequencies within its frequency windows, thus allowing instantaneous selection of any of the 416 frequencies within a 12.5-MHz frequency allocation. The system is described and compared with available alternatives with respect to frequency agility, selectivity, DC to RF efficiency, intermodulation rejection, space utilization, and initial cost. Field testing in a nonwireline system in Portland, OR, USA is described, and the adaptability of the system to present and future frequency planning is discussed.<>
