- Abstract
The frequency modulation (FM) technology is one of the key technologies in telemetry communication. Based on the basic principle of phase-locked loop (PLL) FM, this paper puts focus on the design of a high data rate PLL FM telemetry transmitter, which realizes single-point injection FM of PCM data by utilizing a step adjustable carrier frequency in the S-band. The transmitter is very small and can accept input PCM data rates up to 10Mb/s. Theoretical analysis and experimental results show that the telemetry transmitter using the single-point injection method not only has wideband FM characteristics, but also is able to meet the high-speed data transmission requirements.
