Linear power amplifier
CML Microcircuits
The CMX998 is an integrated solution for a linear based Cartesian Feedback Loop (CFBL) transmitter.
Acting as a direct conversion quadrature mixer from I and Q to RF output, it provides the capability to linearise the Power Amplifier (PA) via feedback from the PA's output.
Included are forward and feedback paths; local oscillator circuitry including loop phase control; an instability detector and uncommitted op-amps for input signal conditioning.
