A81-1 / SMA81-1
Cascadable Amplifier
20 to 250 MHz
Rev. V3
Features
• High Reverse Isolation : >30 dBm (TYP.)

• High Gain: 25 dB (TYP.)
• High Level Output: +13.5 dBm (TYP.)
Description
The A81-1 RF amplifier is a discrete hybrid design, which
uses thin film manufacturing processes for accurate
performance and high reliability.
The 2 stage silicon bipolar feedback amplifier design
displays impressive performance over a broadband
frequency range. An isolation transformer is used in the
feedback loop, with the benefit of high reverse isolation.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is
available.
