Output Transformer
Matching the output of the ARA2004 to a 75 Ohm
load is accomplished using a 2:1 turns ratio
transformer. In addition to providing an impedance
transformation, this transformer provides the bias to
the output amplifier stage via the center tap.
The transformer also cancels even mode distortion
products and common mode signals, such as the
voltage transients that occur while enabling and
disabling the amplifiers. As a result, care must be
taken when selecting the transformer to be used at
the output. It must be capable of handling the RF
and DC power requirements without saturating the
core, and it must have adequate isolation and good
phase and amplitude balance. It also must operate
over the desired frequency and temperature range
for the intended application.
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. Although the
ARA2004 has some built-in ESD protection, proper
precautions
and
handling
are
strongly
recommended. Refer to the ANADIGICS application
note on ESD precautions.
