ABSTRACT:
A power divider includes first and second amplifiers (AMP1, AMP2), and an isolation circuit. AMP1includes a first capacitor (C1) with one end connected to input, a first FET (FET1) having a gate connected to the other end of C1, a first feedback circuit connecting the FET1drain and the one end of C1, a first source circuit connecting the FET1source and ground, and a second capacitor connecting the FET1drain and a first output. AMP2includes a third capacitor with one end connected to input, a second FET (FET2) having a gate connected to the other end of the third capacitor, a second feedback circuit connecting the FET2drain and the one end of the third capacitor, a second source circuit connecting the FET2source and ground, and a fourth capacitor connecting the FET2drain and a second output. The isolation circuit connects the FET1and FET2sources.
