Coupler with distributed feeding and compensation
Abstract:
The embodiments described herein can provide improved signal feeding between hybrid couplers and associated transistors. As such, these embodiments can improve the performance of amplifiers and other such RF devices that utilize these components. In one embodiment a device includes a distribution network and a compensation resonator. The distribution network is configured to output a signal through a relatively wide output feedline. This relatively wide output feedline provides distributed signal feeding that can improve signal distribution and performance. The output feedline is coupled to the compensation resonator. In general, the compensation resonator is configured to resonate with the distribution network at the frequency band of the signal. Thus, the distribution network and compensation resonator together can provide improved signal distribution while maintaining performance at the frequencies of interest.
