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.
