600MHz Current Feedback
Amplifier with Compensation Pin

Description

The HFA1102 is a high speed wideband current feedback
amplifier featuring a compensation pin for bandwidth limiting.
Built with Harris’ proprietary complementary bipolar UHF-1
process, it has excellent AC performance and low distortion.

Because the HFA1102 is already unity gain stable, the
primary purpose for limiting the bandwidth is to reduce the
total noise (broadband) of the circuit. The bandwidth of the
HFA1102 may be limited by connecting a capacitor and
series damping resistor from pin 8 to ground. Typical
bandwidths for various values of compensation capacitors
are shown in the Electrical Specifications section of this
datasheet.

A variety of packages and temperature grades are available.
See the ordering information below for details.
