AGC circuit classification and AD8347 quadrature demodulation chip design

1. Working principle of AGC circuit 1.1 application of GC circuit With the deterioration of the electromagnetic environment, the crosstalk between different frequency bands of electromagnetic signals, as well as the possible human interference, will lead to a large dynamic range of the signal at the input port of the receiver. Once the circuit saturation […]

Line synchronization code power (sync) based on calculation_ DL) module

1. Introduction Most receivers have to deal with signals with large dynamic range, which requires gain adjustment to prevent overload or intermodulation of a certain stage, and adjust the work of demodulator to optimize the work. In modern radio receiver. Variable gain amplifiers are electronically controlled, and when attenuators are used in receivers, they are […]
