4. Descrizione Generale
The HC08CH-FM , manufactured by R.V.R. Elettronica, is a hybrid coupler made
with new concept technology. Its function is to take the RF signal coming from a
maximum of eight external sources and combine its outputs to a single antenna
output (or two outputs if the option is present) or to slotted cables. The HC08CH-
FM
combines up to eight sources of 150 W max power (150 W total).
The HC08CH-FM is designed to be contained in a 2HE 19” rack box.

4.2 Features
The nominal operation of a transmitter based on a hybrid combiner scheme such
as the HC08CH-FM requires the sources to deliver the same power. Any power
differences (or phase shifts) between the amplifiers produce so-called “imbalance
power”, which is partly dissipated inside the combiner; the loss is equal to 9dB
maximum in the final combination. The HC08CH-FM guarantees operation of the
transmitter even if one of the amplifiers is completely out of service. In which case,
the power coming from the surviving amplifier is transmitted to the antenna, except
for a fraction of it (about 1/4) which is dissipated inside the combiner.
The status of the equipment is indicated by a LED on the front panel: ON/OFF .
The HC08CH-FM can be connected in cascade to the exciters via an interlock
cable, so as to be able to deactivate the power delivery of the exciter in the event
of malfunctions in the transmission system.
