Overview:
Wide Bandwidth Wireless Transmitters commonly use analog quadrature modulators (AQM) to convert composite (I + j*Q) baseband signals to radio frequency (RF). The AQM contains a local oscillator (LO) input, a phase splitter that generates two LO 90 degrees out of phase, two mixers (each mixer mixes the baseband signal to RF) and a combination of two Adder of signals (Figure 1).Previous:24V to 5V circuit diagram
