MGA-61563 Current-Adjustable, Low Noise Amplifier
Data Sheet
Description
Avago Technologies' MGA-61563 is an economical, easy-to-use GaAs MMIC amplifier that offers excellent linearity and low noise figure for applications from 0.1 to 6 GHz. Packaged in an miniature SOT-363 package, it requires half the board space of a SOT-143 package.
One external resistor is used to set the bias current taken by the device over a wide range. This allows the designer to use the same part in several circuit positions and tailor the linearity performance (and current consumption) to suit each position. The MGA-61563 is normally operating with Id set in the 20-60mA range
The output of the amplifier is matched to 50Ω (below 2:1 VSWR) across the entire bandwidth and only requires minimum input matching.
