Performance & Technology
FM Compact Transmitters RS-3000 Series is a range of modular broadcast FM transmitters designed to operate in the whole 87.5–108 MHz frequency range for FM radio broadcasting, with power range 3000, 3500, 4000, 5000W and 6000W. Superior audio quality and sound purity — High Power 5kW FM Transmitter Broadcast Equipment.
- Very high efficiency — more than 75% for a complete 3 kW amplifier
- Latest LDMOS technology for power modules, ultra-high RF efficiency (>80% typ.), software optimized for each power level
- Lowest weight and dimensions in the industry — lower heating, lower space occupied, lower maintenance needed
- Longer component lifespan, reduced electricity and cooling costs, fewer fans required
Key Features
- Analog and digital (AES/EBU) audio signal input directly
- 5-inch color LCD with touch panel displays all parameters in real-time
- Intelligent protection: over PF, over SWR, over temperature, voltage, current
- Real hot-plug structure — modules can be repaired without stopping the transmitter
- RS232/RS485 and TCP/IP communication interface ready for remote control
Protection System
Over/Under Voltage DC & AC, RF and power supply over-temperature, RF coaxial output open or short circuit protection. Capable of long working time on short/open loads at all phase angles without damage. Integrated AC mains filtering and lightning protection, with delayed re-energizing after mains power blackout to prevent damage from voltage peaks.
Everything You Need to Go On Air
The transmitter alone isn't enough. A functioning FM broadcast station requires three core components working together. We supply all of them -- properly matched and tested as a system.
Signal Chain Overview
3KW FM Transmitter
The heart of your broadcast system. Converts audio to a high-power FM signal ready for transmission. Includes all audio inputs, control interfaces, and protection systems.
- Solid-state LDMOS amplifiers
- Built-in DSP stereo processor
- Remote monitoring via Ethernet
FM Broadcast Antenna
Radiates your signal in all directions with maximum efficiency. Antenna gain and height directly determine your coverage radius -- the right antenna can double your effective range.
- FM Dipole Antenna
- Matched to 3KW power rating
- Stainless steel construction
Low-Loss Coaxial Cable
Carries the RF signal from transmitter to antenna with minimal power loss. For 3KW systems, we recommend 1-5/8" low-loss coaxial cable to preserve your full output power.
- 1/2”, 1-5/8" or 7/8" options
- Pre-terminated connectors
- Custom lengths available
