Ku-band RF PLLs have integrated VCO for low phase-noise local oscillator circuits

The TFF100xHN family of Ku-band RF PLLs has integrated VCO intended for low phase-noise local oscillator (LO) circuits in Ku-band VSAT transmitters and transceivers. Manufactured in a high-performance ...

Understanding The Quartz Crystal Resonator

Thus an RF oscillator using a tuned circuit can drift by many kHz over the period of its operation, and its timing can not be relied upon. Long before accurate timing was needed for computers, the ...
