Output Transformer

Matching the output of the ARA2000 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.

Proper

precautions

and

handling

are

strongly

recommended. Refer to the ANADIGICS application

note on ESD precautions.
