AH101
Product Description
The AH101 is a medium power gain block that
offers excellent dynamic range in a low cost surface mount package. The combination of a single supply voltage and an unconditionally stable internally matched device, makes it ideal for
both narrow band and broadband applications.
Superior thermal design allows the product to
achieve +45 dBm OIP3 performance at a
mounting temperature of +85°C with an associated MTBF of >100 years
