Abstract
Techniques and architecture are disclosed for providing an ultra-wideband, multi-channel solid-state power amplifier architecture. In some embodiments, the architecture includes a power divider which splits an input signal and delivers that split signal to a plurality of downstream channel chipsets. Each channel chipset is configured to amplify a sub-band of the original full-band input signal and to provide the resultant amplified sub-band for downstream use, such as for transmission by an antenna operatively coupled with that channel. In the aggregate, the amplified sub-bands provide coverage of the same ultra-wideband frequency range of the original input signal, in some cases. In some embodiments, the architecture provides high radio frequency (RF) power with good amplifying efficiency and ultra-wide instantaneous frequency bandwidth performance in a small-form-factor package. In some instances, control circuitry is provided to control which chipset die(s) are enabled/disabled, thus providing control over gain and power levels of the output signal(s).
