Overview

This product has a simple structure, excellent performance, stable operation, and easy maintenance. Its main technical features are:
1) Adopting full digital processing encoding and modulation technology, the 3U chassis integrated machine integrates the exciter with power amplifier, control, power supply and other modules in a 3U height chassis, suitable for mass production, with good consistency and stable indicators.
2) The motherboard adopts a brand new direct RF output architecture, with excellent performance, simple and fast frequency adjustment, and good frequency consistency throughout the entire FM frequency band.
3) The FM radio transmitter adopts a brand new full broadband loop scheme, which has precise power detection (power detection error ± 10%, typical value ± 5%) and loop control function throughout the entire FM frequency band.
4) Adopting touch screen display and input operation, the operation is intuitive and simple.
