plot(mnl) plots the output signal power and the phase change versus the input signal power. This syntax is equivalent to plot(mnl,'Pout'). plot(mnl,'Gain') plots the gain and the phase change …

How to plot the AM-AM and AM-PM plots? The AM-AM and AM-PM plots are based on a model that assumes the input to the power amplifier is a single unmodulated tone. According to the …

2024年10月24日 · The plot is called the AM-to-AM (AM-AM) response (the amplitude-dependent amplitude response) of the amplifier. The AM-AM characteristic is linear at low input powers, …

The AM/AM characteristic of the DUT is obtained by plotting the magnitude of its instantaneous gain (|G(|x in |)|), typically expressed in dB, as a function of the DUT’s instantaneous input …

This example shows how to characterize a power amplifier (PA) using measured input and output signals of an NXP Airfast PA. Optionally, you can use a hardware test setup including an NI …

2024年11月21日 · I have .txt files that contain complex input and output baseband signals of an amplifier. I need to plot the AM/AM (magnitude of Gain vs. Input power) and AM/PM (phase of …

amplitude-to- amplitude modulation (AM/AM) and amplitude-to-phase modulation (AM/PM) effects of the PA are estimated.These estimat-ed distortions are then removed from the PA by pre …

2020年4月1日 · AM（Amplitude Modulation）调制是一种常见的模拟调制技术，通过改变载波信号的幅度来传输基带信号。 在 AM 调制 中，基带信号被乘以一个高频载波信号，产生一个带有 …

2011年7月11日 · I have designed a Power Amplifier and have obtained AM-AM and AM-PM plots. I would like to include the S21 parameter file (which has both am-am and am-pm) and run …

To get the AM-AM and AM-PM results, two signals are used. One is the reference signal, which is the PA input signal. The other is the PA output signal, for which the IQ waveform data is …
