S76005 500w FM Broadcast Transmitter 500 Watt

The S76005 500W FM broadcast transmitter is an evolution of the highly modular architecture for which Eddystone Broadcast transmitters are known. The use of 300W hot-pluggable Power Amplifier modules means that removal of amplifiers can be carried out with minimal reduction in output power.
The design also features highly efficient 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
S76005 500w FM Broadcast Transmitter 500 Watt
The drive input is fed to an internal 2 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 1 or 2 (option) 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.
Outputs from the 2 Power modules are combined via a highly efficient 2 way common rail Wilkinson combiner. The
combined RF output is then fed to the output coupler and harmonic filter.
