4.1 General Description
PJ500C-LCD, PJ700C-LCD
e
PJ1000light
are compact
radio broadcasting
amplifier
manufactured by
R.V.R. Elettronica SpA
featuring adjustable RF power
output up to 500, 700 and 1000 W, respectively, under 50 Ohm standard load and
less than 20W drive power requirement.
PJ500C-LCD, PJ700C-LCD
and
PJ1000light
have been designed for installation
in a 19”x3HE box for rack.
These amplifiers incorporates a low-pass filter to keep harmonics below the limits
provided for by international standards (CCIR, FCC or ETSI).
Two major features of
PJ500C-LCD, PJ700C-LCD
and
PJ1000light
are compact
design and user-friendliness. Another key feature is its modular-concept design:
the different functions are performed by modules with most connections achieved
through male and female connectors or through flat cables terminated by
connectors. This design facilitates maintenance and module replacement.
The RF power section of
PJ500C-LCD
uses two MOSFET modules delivering up
to 300W output power each,
PJ700C-LCD
uses two MOSFET modules delivering
up to 350W output power each, whereas
PJ1000light
features three MOSFET
modules with up to 350 W output power each.
An LCD on the front panel and a push-button panel provide for user interfacing with
the microprocessor control system, which implements the following features:
• Output power setup
• Power output enable/disable
• User-selectable threshold settings for output power alarm (Power Good
feature)
• Measurement and display of amplifier operating parameters
• Communication with external devices, as programming systems or telemetry
systems through RS232 or I
