The Newglee NGA-201F DRM FM Modulator supports the DRM standard ETSI ES 201 980 and is designed to convert data streams from a media encoder into RF signals. It features modules for DRM baseband processing, digital signal synthesis, frequency conversion, DAC, RF output, audio signal input/output, monitoring system, and control panel.
Digital Pre-Distortion: Optimizes signal quality through compensation.
DRM Modulation Support: Uses Mode E modulation to generate standard RF signals from MDI/DCP streams.
High Performance Processing: Digital signal processing algorithms and Digital Pre-Distortion (DPD) to optimize system performance.
Frequency Synthesis: Direct digital frequency synthesis maximizes RF domain proximity, supporting the 87–108 MHz band.
Network Management: Supports remote control via Web, RS232/RS485, and firmware can be upgraded over the network.
Reliable Operation: GPS synchronization supports SFN/MFN operation, ensuring seamless long-term operation.
Spectrum Optimization: Advanced windowing and filtering algorithms ensure signal purity.
Dual MDI Input: MDI/DCP streams.
Modulation Parameters: Bandwidth 100kHz, Interleaving depth 0.6s.
