Descripción
Today, there is an increasing demand for wideband, high power solid state amplifiers operating in the microwave and millimeter wave frequency ranges. Normally, a single solid-state power amplifier (SSPA) module is not able to supply enough power level, making it necessary to combine various modules to achieve the required level. Amongst the different configurations, radial combiners exhibit a number of advantages over the corporate or chain-type combiners, mainly when a large number of ports (N) are considered. In this work, two E-plane radial power combiners using the very low loss TE01 circular waveguide mode have been designed, manufactured and measured. The first is a 16-way Ku-band combiner, showing an excellent performance: the experimental prototype has a return loss better than 30 dB, with a balance for the amplitudes of (±0.15 dB) and (±2.5o) for the phases, in a 16.7% fractional bandwidth (2 GHz centered at 12 GHz) and efficiency better than 95% in the whole band. The second is a 5-way W-band combiner, showing again remarkable characteristics: the experimental prototype has a return loss better than 20 dB, with a balance for the amplitudes of (±0.4 dB) and (±3.5o) for the phases, in a 12.8% fractional bandwidth (12 GHz centered at 94 GHz) and efficiency better than 85% in the whole band. In both cases the experimental results are state-of-art in the field.
