    摘要: A RF input signal system and method switches the RF input signal amplified by an amplifier PA1 or PA2 to be present only in great magnitude at the summing port of a hybrid combiner H2 when the SPDT switch SW1 is directing the “RF in” signal to the summing port of the hybrid divider H1, while the balancing port of H1 is terminated by the switch SW1. The benefit of switching between H and V ports by using this method eliminates the insertion losses of the switch SW1 and isolators ISO1 and ISO2 of the prior art. The benefit is also the speed of switching which can now be executed much faster (in nanoseconds) in comparison to the method shown in FIG. 1 where the limiting factor are the PIN diodes used in such devices (SW1 of FIG. 1) that only allows switching transients in tens of microseconds only. The non-summing port of H2 is then only radiating much less energy of −20 to −30 dB below that of the summing port.

    摘要: High efficiency Doherty amplifiers are described. Contemplated Doherty amplifiers can include an input hybrid coupler having first and second inputs, and first and second drivers that individually drive respective first and second inputs. In this manner, the driver output power to the main and auxiliary amplifiers can be dynamically controlled as a function of an input signal's envelope. This advantageously allows for a substantial decrease in the amount of power wasted by the driver, especially when used with digitally modulated signals.

    摘要: The present invention relates to an amplifier circuit where a load modulation is applied to a segmented amplifier. This will reduce the shunt loss since the loss of a segmented amplifier is reduced by allowing each amplifier segment or combination of segments to operate to their full output power capacity, rather than limited to a lower output power which results in a higher shunt loss. Hence, operation to full capacity before adding more segments is made possible by dynamically modulating the load.
