APPLICATION INFORMATION
Printed Circuit Board Layout Considerations
The ARA05050 is a high-performance RF device.
Special consideration must be given to certain
features of the the printed circuit board layout, as
they can affect the RF performance of the IC. Refer to
the ANADIGICS application note “CATV Reverse Amp
w/ Step Attenuator” for more details.
Amplifier Enable / Disable
The ARA05050 includes two amplification stages that
each can be shut down through external control pins
V
REF
1
and V
REF
2
(pins 5 and 19, respectively.) By
applying a typical bias of 1.75 Volts to these pins, the
amplifiers are enabled. In order to fully disable an
amplifier, its control pin requires a negative bias of
-1.5 to -2.0 Volts.
Amplifier Bias Current
The I
SET
pins (11 and 25) set the bias current for the
amplification stages. Grounding these pins results
in the maximum possible current. By placing a
resistor from the pin to ground, the current can be
reduced. The recommended bias conditions use
the configuration shown in the test circuit schematic
in Figure 4.
Thermal Layout Considerations
The device package for the ARA05050 features a heat
slug on the bottom of the package body. Use of the
heat slug is an integral part of the device design.
Soldering it to the ground plane of the PC board will
ensure the lowest possible thermal resistance for
the device, and will result in the longest MTF (mean
time to failure.)
A PC board layout that optimizes the benefits of the
heat slug is shown in Figure 13. The via holes located
under the body of the device must be plated through
to a ground plane layer of metal, in order to provide
sufficient thermal conductivity. The recommended
solder mask outline is shown in Figure 14.
ESD Sensitivity
Electrostatic discharges can cause permanent
damage to this device. Electrostatic charges
accumulate on test equipment and the human body,
and can discharge without detection. Proper
precautions
and
handling
recommended. Refer to the ANADIGICS application
note on ESD precautions.
