• Operating frequency: 0.1 GHz ~ 6.0 GHz • Noise figure: 1.2 dB at 800 MHz 1.4 dB at 1900 MHz • Gain: 17.5 dB at 800 MHz 15.7 dB at 1900 MHz • Bypass switch on chip Loss = typ 1.6 dB (Id < 5 A) IIP3 = +10 dBm • Adjustable Input IP3: +2 to +14.7 dBm • Miniature package: 1.4 mm x 1.2 mm 2.7 V to 5.0 V operation
Hewlett-Packard's MGA-81563 is an economical, easy-to-use GaAs MMIC amplifier that offers excellent power and low noise figure for applications from 0.1 to 6 GHz. Packaged in an ultraminiature SOT-363 package, it requires half the board space of a SOT-143 package.
The output of the amplifier is matched to 50 W (better than 2.1:1ÊVSWR) across the entire bandwidth. The input is partially matched to 50 W (better than 2.5:1ÊVSWR) below 4 GHz and fully matched to 50 W (better than 2:1 VSWR) above. A simple series inductor can be added to the input to improve the input match below 4 GHz. The amplifier allows a wide dynamic range by offering a 2.7 dB NF coupled with a +27 dBm Output IP3.
The circuit uses state-of-the-art PHEMT technology with proven reliability. On-chip bias circuitry allows operation from a single +3ÊV power supply, while resistive feedback ensures stability (K>1) over all frequencies and temperatures.
