Abstract

A technique is proposed for monitoring the parameters of an amplifier according to its power consumption during amplification of a dual-frequency test signal. A block diagram for monitoring the parameters of a radio transmitter amplifier in transient modes has been developed. The results of testing a broadband amplifier are presented in order to achieve equally high parameters over the entire operating frequency range. A technique has been developed for testing an amplifier in a mode with automatic mode control using a deterministic dual-frequency test signal, which makes it possible to simplify equipment testing and evaluate the power consumption of the output stage. A software has been developed to automate the process of measuring the electrical parameters of power amplifiers, which allows connecting the devices with programmed control, defining the settings of connected devices, set the frequency range in which measurements are to be taken and the measurement pitch. The program is designed to carry out automated measurements of the output power, linearity, spurious radiations of an amplifier in a given frequency range and generate a report on the measurements.

无线电发射机功率放大器瞬态模式参数监测

提出了一种根据放大器在放大双频测试信号时的功耗来监测放大器参数的方法。给出了一种监测无线电发射机放大器在瞬态模式下参数的框图。为了在整个工作频率范围内获得同样高的参数，给出了对宽带放大器的测试结果。本文提出了一种利用确定性双频测试信号对具有自动模式控制模式的放大器进行测试的技术，从而简化了设备测试和对输出级功耗的评估。已经开发了一种软件来自动测量功率放大器的电气参数，它允许将设备与编程控制连接，定义连接设备的设置，设置要进行测量的频率范围和测量间距。该程序设计用于在给定频率范围内对放大器的输出功率、线性度、杂散辐射进行自动测量，并生成测量结果报告。
