6Ax MGA-61563 Current-Adjustable, Low Noise Amplifi er Data Sheet Description Features Single +3V or + 5V supply Avago Technologies MGA-61563 is an economical, easy-to-use GaAs MMIC amplifi er that off ers excellent High linearity linearity and low noise fi gure for applications from 0.1 Low noise fi gure to 6 GHz. Packaged in an miniature SOT-363 package, it Miniature SOT363 (SC70) package requires half the board space of a SOT-143 package. Unconditionally stable One external resistor is used to set the bias current taken by the device over a wide range. This allows the Lead-free option available designer to use the same part in several circuit posi- tions and tailor the linearity performance (and current Specifi cations at 2 GHz 3V, 41 mA (Typ.) consumption) to suit each position. The MGA-61563 is normally operating with Id set in the 20-60mA range 28.5 dBm OIP3 1.2 dB noise fi gure The output of the amplifi er is matched to 50 (below 2:1 VSWR) across the entire bandwidth and only requires 16.6 dB gain minimum input matching. The amplifi er allows a wide 15.8 dBm P 1dB 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 Package Diagram bias circuitry allows operation from a single +3V or +5V power supply, while internal feedback ensures stability (K>1) over all frequencies.
