MGA-85563 Datasheet | Avago Technologies

Description Avago’s MGA-85563 is an easy-to-use Ga As 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 d B and associated gain of 18 d B 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 d Bm to +17 d Bm. 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.
