S7605C 5kW Compact FM Transmitter
The S7605C Compact FM transmitter 5kW is an evolution of the highly modular
architecture for which Eddystone Broadcast transmitters are legendary. The
use of new higher efficiency 300W hot-pluggable Power Amplifier modules
means that removal of amplifiers can be carried out with minimal reduction in
output power. The design additionally features hot-pluggable switched mode
power supplies which also provide ease of servicing.
Both PA and SMPSU modules are common to the entire 7600 range from
500W to 20kW, resulting in greatly reduced spares holding costs for networks
and groups.

System Overview
The drive input is fed to an internal 16 way splitter which provides the PA module input drive. Each E2021 Power amplifier uses dual packaged MOSFET's mounted on a substantial heatsink assembly with minimum airflow over RF components. DC power is fed to the RF modules from the 8 switched mode power supplies. Internal control and self protection in case of reverse power, excess current or over temperature is handled within each individual E2021 power amplifier module with all monitoring being microprocessor derived. Each module transmits its internal parameters to the central transmitter controller/monitor (E2023) and parameters are displayed on an easy to read backlit LCD screen.
Cooling Systems
The S7605C transmitter has self contained redundant cooling fans mounted on the rear of the transmitter. This cooling
system can be ducted if required and bespoke systems can be provided to meet special requirements.
