MGA87563

0.5 – 4 GHz 3 V Low Current GaAs MMIC LNA Technical Data MGA-87563 Features Ultra-Miniature Package 1.6 dB Min. Noise Figure at 2.4 GHz 12.5 dB Gain at 2.4 GHz Single +3 V or 5 V Supply, 4.5 mA Current Surface Mount SOT-363 (SC-70) Package Description Agilent’s MGA-87563 is an economical, easy-to-use GaAs MMIC amplifier that offers low noise and excellent gain for applications from 0.5 to 4 GHz. Packaged in an ultra-miniature SOT-363 package, it requires half the board space of a SOT-143 package. With the addition of a simple shunt-series inductor at the input, the device is easily matched to achieve a noise of 1.6 dB at 2.4 GHz. For 2.4 GHz applications and above, the output is well matched to 50 Ohms. Below 2 GHz, gain can be increased by using conjugate matching. The circuit uses state-of-the-art PHEMT technology with selfbiasing current sources, a sourcefollower interstage, resistive feedback, and on-chip impedance matching networks. A patented, on-chip active bias circuit allows operation from a single +3 V or +5 V power supply. Current consumption is only 4.5 mA, making this part ideal for battery powered designs.
