| Description: |
This transmitter implements a
digital FM modulator module as its core, combined
with a RF power amplifier. DSP & DDS are used to execute all-digital
processing, such as digital filtering, pre-emphasis, pilot
generation, stereo coding and FM modulation. AGC circuitry is
used to keep the set power stable. High performance and
very good reliability has been proved by the large usage of
ZHC-300W-TX transmitters. Also, it is very affordable and
small in size.
