Vox Amplifier
is a robust source of RF
power for ultrasonic, laser
modulation, RFI/EMI, plasma
generation,
laboratory
and
general industrial applications.
Featuring leading edge solid
state
design
for
all
RF
amplifier stages and a built-in
DDS signal source, it provides
everything for a complete and
reliable, controlled RF power
delivery system. It reflects the
Vox ongoing commitment to
provide RF power products of
t h e
h i g h e s t
q u a l i t y ,
incorporating
the
current
requirements
for
complete
remote
control
and
data
acquisition features.
OPERATION
The Vox Amplifier produces up to
300 Watts of RF power over a
frequency range from lower
than 20 kHz to higher than 4
MHz. It operates over the
entire frequency range without
band
switching
or
other
adjustments. Extended range
to over 10 MHz is possible
with reduced output power.
Gain is rated at 55 dB with a
typical gain flatness of ±1.5
dB.
The Front Panel offers a LCD
display of Forward, Reflected
and Load Power readings, RF
Status, MGC/AGC setups and
operating
frequency
in
Generator Mode.
Power meters are calibrated
into a 50 Ohm Load and are
accurate when unit operates
into matched load. Outside of
matched condition, the model
Vox
Amplifier'
p o w e r
measurement
system
provides an accurate reading
of VSWR.
When used as amplifier, the
Vox Amplifier is compatible with
most signal and function
g e n e r a to r s ,
c o m p u te r
synthesizer cards within its
output and bandwidth limits.
The
Forced-air
cooling
system
and
the
internal
power supply are designed to
permit operation over a wide
range of temperature and
global AC line conditions.
The Vox Amplifier is built to
withstand a +13 dBm (2.8Vp-
p) Input signal. The unit
amplifies the inputs of AM,
FM,
SSB
and
pulse
modulations.
OUTPUT PROTECTION
Vox Amplifier is protected by its
internal control system for
300 Watts of total Forward
Power and 70 Watts of
Reflected Power. This will
protect the amplifier output
stage
from
accidental
overdrive at the input and an
extreme mismatch at the
Output.
GENERAL
Vox's products are designed
to be reliable, compact and
light in weight. The use of
c o n s e r v a t i v e l y
r a t e d
components ensures high
reliability and eliminates the
need for periodic calibration.
