Transmission Gain And Receive Gain Of Power Amplifier

- Sep 06, 2018-

The transmission gain refers to the ratio of the output power of the amplifier to the input power, and the unit is usually expressed in "dB" (decibel). The output gain of the power amplifier increases or decreases as the frequency of the input signal changes. This indicator is the most important basis for assessing the quality of power amplifiers. The smaller the decibel value, the flatter the frequency response curve of the power amplifier, the smaller the distortion, and the stronger the degree of reproduction and reproducibility of the signal.

Receive gain: Gain is one of the main indicators of the antenna. It is the product of the direction coefficient and the efficiency, and is the performance of the antenna radiated or received. The choice of gain size depends on the requirements of the system design for the coverage area of the radio wave. Simply put, under the same conditions, the higher the gain, the farther the distance the radio wave travels. The larger the receiving gain value of the power amplifier, the stronger the receiving performance.
