Satellites are crucial in global communications, necessitating widespread transceiver use. Frequency bands, carefully chosen to prevent interference, employ Phase-Locked Loops (PLLs) as synthesizers. Designing a single-chip PLL for efficient frequency multiplication is vital in today's tech landscape. Literature reveals a gap in research for the Ku band (12-18 GHz), lacking single-chip, wideband PLLs. This work introduces a 12-18 GHz charge pump-based integer-N PLL, compact at 0.

Nowaday, the supper low noise PLL oscillator and the supper low jitter synthesizer have been used in the worldwide communications system. Where, the former is used for the satellite communications and the latter is used for the cellular phone. The main idea to obtain a supper low noise PLL oscillator is to use a high Q resonator, such as the dielectric resonator, with a suitable phase-locked loop.
