HIGH GAIN: 24.5 dB (TYP.)  
Description  
The A82 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  
.
