This Eddystone S7602 2kW FM transmitter is a modular solid-state platform designed for professional broadcasters who need efficient, dependable 24/7 operation in demanding on-air environments.
The unit builds on Eddystone’s proven 7600 series architecture, combining 300W hot-pluggable power amplifier modules, hot-pluggable switched-mode power supplies and intelligent control to keep services on air while simplifying maintenance.
With a compact 19-inch rack footprint and robust construction, it suits regional, community and network sites that require 2kW of RF power with minimal downtime.
At the heart of the system is an internal 8-way splitter feeding multiple E2021 power amplifier modules, each using dual packaged MOSFET devices on substantial heatsinks to optimise cooling and RF stability.
Outputs from the power amplifiers are combined through a highly efficient 8-way common-rail Wilkinson combiner, then routed to the output coupler and harmonic filter to meet stringent spectral purity requirements.
Common PA and SMPSU modules across the 7600 range from 500W to 20kW help network operators minimise spares holdings and standardise maintenance procedures across multiple transmitter sites.
The transmitter integrates comprehensive monitoring and protection, with each E2021 module providing self-protection against reverse power, excess current and over-temperature, and reporting key parameters to an E2023 transmitter controller.
Engineers can access clear status information via the front-panel LCD display, while remote control and monitoring interfaces allow supervision and power adjustment over serial or IP links, depending on controller configuration.
Built-in protection logic maintains full power into loads up to 1.9:1 VSWR before gracefully reducing output to protect RF stages.
RF output is up to 2kW, adjustable down by 6 dB across the 87.5–108 MHz FM broadcast band into a 50 ohm unbalanced load via a 7-16 female DIN RF connector, with 7/8 inch options available on request.
Typical overall efficiency is around 60 percent, supported by power-factor-corrected switched-mode supplies running from a single-phase 176–264 V AC mains input.
Self-contained redundant rear-mounted cooling fans provide reliable airflow and can be ducted or customised to suit specific transmitter room layouts.
These features make the Eddystone S7602 2kW FM Transmitter a strong choice for broadcasters looking for modular, serviceable RF power with consistent on-air performance and low operating costs.
