Annex B: PAC Clip-On Power Amplifiers
B.1 Introduction
The new PAC is a clip-on amplifier which works in the 2 GHz band. It is used
together with SVP Broadcast Microwave’s camera Transmitters, allowing the
coverage of wider areas.
It can be used with nearly all camera Transmitters as it can have V battery
adapter plates. This small and powerful amplifier expands the possibilities of
the wireless camera Transmitters. Just by adding this low weight and compact
amplifier to a camera Transmitter, medium range links can be possible.
This amplifier has a 4 W output and the input signal level has to be in the
range of 10 to 100 mW, as it has 10 dB ALC.
This solid state LDMOS amplifier has been designed and optimized for being
used with COFDM digital video signals. The low intermodulation and our
proprietary pre-distortion technique provide an excellent linearity and better
ACP performance. The pre-distortion technique enables higher power output
maintaining transmitted signal quality.
The amplifier can be powered through the V or through a DC power supply
connector, which accepts input power voltage from 11 to 16 VDC.
The PAC amplifier is protected against polarity reverse and over voltage. It
also has thermal protection with auto reset.
The equipment has also two LEDs (Out, Level and DC), that show the
equipment’s operation state. The information provided by these two LEDs is
described below:
• DC Power Supply Led: green light when the amplifier is powered.
• Output Power Led: green light when the output power is set level.
The low intermodulation, the excellent RF performance and the high reliability
make this amplifier especially interesting for most demanding wireless
camera link applications.
