A new balanced amplifier using 6-port power divider

ABSTRACT A new balanced amplifier using the 6-port power divider is proposed. The power divider used in this balanced amplifier has a totally planar structure, and needs no internal resistor and termination. The measured insertion loss of the 2-port back-to-back power divider/combiner for the balanced amplifier is around 0.7 dB, which is a reasonable value at 10 GHz. In power measurement, the 1 dB output power compression point of the proposed balanced amplifier is twice that of the single-ended amplifier as predicted. The measured performances show that the proposed amplifier can be applied as a new balanced amplifier
