ZHC618F-1000C FM Transmitter
The transmitter implements digital FM modulator module as its core,combining with RF power amplifier.In the transmitter,DSP&DDS are used to execute all-digital processing,such as digital filtering,pre-emphasis,the generation of pilot frequency,stereo coding and FM modulating.A AGC circuit is used to keep the set power stable.
High performance and very good reliability has been proved by the large usage of ZHC618F-1000c transmitters.Also it is low cost and small size.
