Basic Concepts
The RF power amplifier (RF PA) is the main part of the transmission system, and its importance is self-evident. In the front-stage circuit of the transmitter, the RF signal power genera...
IQmath, a fixed-point processor uses this method to process floating-point numbers. I already know some of it, but what do IQ(-0.4), IQ(0.8)... mean? Is there any specific explanation on this?...
1. Causes of waveform disorder: 1. Inconsistent line impedance; 2. Signal reflection; 3. Crosstalk. 2. Solutions to short lines 1. It is easy to occur in QFP with narrow pin spacing 2. Change to large...
