Information
The Model 500A 100A is a self-contained, air cooled,
broadband, completely solid state Radio Frequency
(RF) Amplifier designed for applications where instantaneous
bandwidth and high gain are required.
Push-pull circuitry is utilized in all high-power stages in
the interest o f lowering distortion and improving
stability. The M odel 500A100A, when used with an RF sweep
generator, w ill provide a m inim um o f 500
w atts o f sw ept power.
Special features incorporated into the Model 500A 100A
include the following:
•
A front panel 4-line vacuum fluorescent display (VFD) for m
onitoring am plifier status and forward
or reflected output power.
•
A utom atic Level Control (ALC), which can be controlled by
internal circuits or by an external input
with front panel control o f the ALC Threshold.
•
Pulse input capability.
•
RF output level protection,
•
An internal RF detector, w hich provides an output for use
in self-testing or operational modes.
•
A front panel gain control for adjusting the am plifier’s
gain when operating the am plifier .in the
“M anual” mode.
•
Provisions are m ade for rem ote control o f all operating
functions of the am plifier via IEEE-488
and R S-232 com puter protocols.
Protection is provided by DC current and voltage sensing o f
each o f the final RF am plifier modules.
Housed in a stylish, contem porary cabinet, the M odel
500A100A provides readily available RF power for
typical applications such as RF susceptibility testing,
antenna and component testing, wattm eter
calibration, and use as a driver for higher power amplifiers.
