Address-Programmable Reverse Amplifer with Step Attenuator

ANADIGICS 

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,

ARA2000

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.
