Description
The A81-3 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.

Features
• HIGH REVERSE ISOLATION >35 dBm (TYP.)
• EXCEPTIONAL OUTPUT VSWR 1.1:1 (TYP.)
• LOW NOISE 3.6 dB (TYP.)
• MEDIUM OUTPUT LEVEL +8.0 dBm (TYP.)
