Accurate Power Detection of a CDMA Multi-carrier Power Amplifier Using a Logarithmic Amplifier

The accurate detection of the power output of a multi-carrier CDMA power amplifier enables the enhancement of power efficiency and harmonic suppression. Even though CDMA carriers with equal total power are applied, the experimental results, using a log...

In a typical multi-carrier power amplifier (MCPA) application, it is well known that good amplitude matching and good phase matching are required for greater reduction of intermodulation distortion (IMD) or for better harmonic rejection within the CDMA spectral mask. To solve the mismatching problem, it is desirable to accurately...
