Description
Avago’s MGA-62563 is an economical, easy-to-use GaAs
MMIC ampli er that o ers excellent linearity and low
noise gure 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 ampli er is matched to 50 (below
2:1 VSWR) across the entire bandwidth and only requires
minimum input matching. The ampli er allows a wide
dynamic range by o ering 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.
