ZHC618F-300W FM Professional Radio Transmitter(30W/100W/300W)

FM professional radio transmitter of ZHC618F-300W is an innovation software-radio products.It executes analog FM transmitting through all digital methods.

The transmitter adopts freshly developed digital FM modulate 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.

High performance and very good reliability has been proved by the large usage of ZHC618F-300W transmitters.Also it is low cost and small size.
