A typical example is the
Ophir 5085 broadband amplifier
with 100 Watt saturated power
output, covering the 10 kHz –
200 MHz frequency range. This
small and lightweight amplifier utilizes
Class A/AB linear power devices that provide
an excellent 3rd order intercept point, high
gain (50 dB) and a wide dynamic range. Due
to robust engineering and employment of the
most advanced devices and components, this
amplifier achieves high efficiency operation
with proven reliability. Band-specific
amplifiers are available to 3.2 GHz in
saturated output powers to 2000Watts. Model
4035 is a 100 Watt band-specific amplifier
that covers the 2 – 30 MHz frequency range.
This small and lightweight amplifier

Modules
Broadband module solutions range in
frequency from 150kHz to 6.4GHz in output
power levels from 1 Watt to 100 Watts. Built
for continuous duty cycle over the specified
frequency range, applications include EMI/RFI
testing, lab test and measurement, and PIM
testing. These broadband modules are
preferred by universities for their
laboratory applications. Band-specific
modules are optimized for power and
linearity over a finite frequency range.
Modules are available in frequency ranges of
1.0MHz to 6.4GHz in output levels from 1
Watt to over 150 Watts. Some of these
band-specific modules have instantaneous
bandwidths within the specified frequency
range - utilized for military and commercial
communication applications. Other
applications include laboratory testing, GSM,
PCS, WLL, UMTS, radar, jamming, and EW/ECM.
Amplifier Sub Systems
Subsystems are integrated solutions for
requirements that fall outside of the normal
19" rack chassis and standard module
configurations. The driver module provides
the power amplifier with higher gain and
output power. Adequate cooling is mandatory
for PA and driver module applications - thus
these subsystems have matched heatsinks that
provide the required cooling. Fans can be
wired into the subsystem if needed, and the
compliant power supply will provide DC Input
of 12-13VDC or 24-28VDC depending on the
frequency range.
