RF amplifier integrated circuit - CMX998
The CMX998 is an inventively engineered solution meant for line-based Cartesian Feedback Loop (CFBL) transmitter. It acts as a direct converter cum quadrature mixer ranging from I and Q to RF output. It also has the capability of providing a linearised Power Amplifier (PA) through the feedback from the PA's output.These also include forward and feedback paths that would oscillate locally or in the form of the circuit that would include loop's phase control along with an instability detector.
