| Abstract: | The FM technology is one of the key technologies in telemetry communications.In this paper,the basic working principle and theoretical analysis of the quasi two-point injected PLL-FM transmitter are given.Then the particular circuit scheme of the transmitter is presented.The test results of the transmitter show that the phase noise is-83.3dBc@10kHz and the spur suppression exceeds 70dBc.The theoretical analysis and experiments both demonstrate that the quasi two-point injected PLL-FM transmitter takes on th... |
