Hi All,
I am working on a L Band Power amplifier. I use Quadrature hybrid dividers and combiners for balanced operation. To obtain better Harmonics rejection at the output I am planning to use modified Quadrature Hybrid which will provide more than 20dB Secong harmonic rejection. My doubt is if I do so , will the reflected second harmonic will harm the high power amplifier. ( I am using 1000W Power amplifier MRF6VP121KH from freescale).
