MGA-68563

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 50Ω (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-ofthe-art E-pHEMT technology with proven reliability. Onchip bias circuitry allows operation from a single +3V power supply, while internal feedback ensures stability (K>1) over all frequencies for Id at 10mA and above. Features Single +3V supply High linearity Low noise figure Miniature package Unconditionally stable Specifications at 500 MHz; 3V, 10 mA (Typ.) 1.0 dB noise figure 20 dBm OIP3 19.7 dB gain * This represents what Avago Technologies has managed to achieve on a device level with trade off between optimal NF, Gain, OIP3 and input return loss.
