Eddystone S7610C

10kW Modular FM Amplifier

The Eddystone S7610C-10 FM amplifier is an evolution of the highly modular architecture for which Eddystone Broadcast transmitters are legendary.

SKU: 103199


The Eddystone S7610C is a 10kW FM transmitter known for its highly modular architecture and efficient design. Here are the key features and specifications:


  1. Modular Design: Utilizes hot-pluggable Power Amplifier modules, allowing for easy removal and servicing with minimal reduction in output power.
  2. Efficient Power Supplies: Incorporates hot-pluggable switched mode power supplies (SMPSU) for efficient operation and ease of servicing. These modules are common across the entire 7600 range, reducing spare holding costs.
  3. N Way RF Power Combining System: Features Eddystone’s patented N way RF power combining system for enhanced performance and reliability.
  4. Compact and Replaceable Modules: Amplifier and PSU modules are compact and replaceable on air, ensuring minimal downtime during maintenance.
  5. Compliance: Fully compliant with ETS 300 384 specification for FM transmitters.
  6. System Flexibility: Easily configurable into a wide range of system architectures to meet specific broadcasting needs.
  7. Remote Control and Monitoring: Comprehensive remote control and monitoring facilities for efficient operation and maintenance.
  8. LCD Display: Equipped with an LCD display for easy local monitoring of parameters.

System Overview:

  • Drive Input: Input is fed to dual 18-way splitters, providing the PA module input drive.
  • Power Amplifiers (E2021): Each E2021 Power amplifier utilizes dual packaged MOSFETs mounted on a substantial heatsink assembly. Internal control and self-protection mechanisms are integrated into each module.
  • Combining System: Outputs from the power modules are combined via the N-way combiner before being fed to the output coupler and harmonic filter.
  • Cooling: Self-contained redundant cooling fans are mounted on the rear of the transmitter. Ducting options are available, and bespoke cooling systems can be provided for special requirements.


  • Power Output: 10kW (Adjustable to -6dB)
  • Operating Frequency: 87.5 to 108 MHz
  • RF Output Load Impedance: 50 ohm unbalanced
  • RF Output Connector: 1-5/8″ EIA
  • Maximum VSWR: Able to maintain full power at 1.9:1 before protection cuts in
  • Mains Power Supply: Three-phase & neutral 380-440V (Other supply voltages available on request)
  • RF Harmonic Output: Better than or equal to –86dBc
  • Ambient Temperature Range: 0°C to +55°C at an altitude up to 3000M
  • Overall Efficiency: Typically 60%

This transmitter is designed for high-power FM broadcasting applications, offering reliability, efficiency, and ease of maintenance.
