MGA-62563
Current-Adjustable, Low Noise Amplifier
Data Sheet
Description
Avago’s MGA-62563 is an economical, easy-to-use GaAs
MMIC amplifier that offers excellent linearity and low
noise figure for applications from 0.1 to 3.5 GHz. Pack-
aged 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 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 0.9 dB NF coupled with a
+32.9 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
supply, while internal feedback ensures stability (K>1)
over all frequencies.
