MGA-68563
Current-Adjustable, Low Noise Amplifier
Data Sheet
Description
Avago Technologies MGA-68563 is an economical, easy-
to-use GaAs MMIC amplifier that offers excellent linearity
and low noise figure for applications from 0.1 to 1.5 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 from
5mA to 30mA. 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 output of the amplifier is matched to 50: (below
2:1 VSWR) across the entire bandwidth and only requires
minimum input matching. The amplifier allows a wide
dynamic range by offering a 1.0 dB NF coupled with a
+20 dBm Output IP3. The circuit uses state-of-the-art
E-pHEMT technology with proven reliability. On-chip bias
circuitry allows operation from a single +3V power sup-
ply, while internal feedback ensures stability (K>1) over
all frequencies for Id at 10mA and above.
