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 amplifi er is matched to 50Ω (below
2:1 VSWR) across the entire bandwidth and only requires
minimum input matching. The amplifi er allows a wide
dynamic range by off ering a 1.2 dB NF coupled with a
+28.5 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 or +5V
power supply, while internal feedback ensures stability
(K>1) over all frequencies.
