Description

The A70 RF amplifier is a discrete hybrid design, which uses

thin film manufacturing processes for accurate performance and

high reliability.

This single stage bipolar transistor feedback amplifier design

displays impressive performance over a broadband frequency

range. Use of an impedance transformer offers the benefit of

high dynamic range and high efficiency.

Both TO-8 and Surface Mount packages are hermetically

sealed, and MIL-STD-883 environmental screening is available
