MGA-85563

MGA-85563 3-volt, Low Noise Amplifier for 0.8 – 6 GHz Applications Data Sheet Description Avago’s MGA-85563 is an easy-to-use GaAs RFIC amplifier that offers low noise figure and high gain from 0.8 to 6 GHz. Packaged in an ultraminiature SOT-363 package, it requires half the board space of a SOT-143 package. The MGA-85563 features a minimum noise figure of 1.6 dB and associated gain of 18 dB at 1.9 GHz. The output is matched internally to 50Ω, and the input is partially matched, requiring only a single external inductor for optimal performance. The supply current can be adjusted using an external resistor, varying IP3 from +12 dBm to +17 dBm. The circuit uses state-of-the-art PHEMT technology with proven reliability. On-chip bias circuitry allows operation from a single +3 V supply, while resistive feedback ensures stability (K > 1) over frequency and temperature.
