MGA-631P8 Datasheet | Avago Technologies

Description Avago Technologies’ MGA-631P8 is an economical, easyto-use Ga As MMIC Low Noise Amplifier (LNA) with active bias. The LNA has low noise with excellent input return loss and high linearity achieved through the use of Avago Technologies’ proprietary 0.5um Ga As Enhancementmode p HEMT process. The LNA has an extra feature that allows a designer to adjust supply current and gain externally. Due to the high isolation between the input and output, gain can be adjusted independently through a resistor in series with a blocking capacitor from the output pin to FB1 pin, without affecting the noise figure. It is housed in a miniature 2.0 x 2.0 x 0.75mm3 8-pin Thin Small Leadless Package (TSLP) package. The pact footprint and low profile coupled with low noise, high gain, excellent input return loss and high linearity make the MGA-631P8 an ideal choice as an LNA for cellular infrastructure for GSM, CDMA, GPS and ISM applications. It is designed for optimum use between 400MHz to 1.5GHz. For optimum performance at higher frequency from 1.4GHz to 3GHz, the MGA-632P8 is remended. Both MGA-631P8 and MGA-632P8 share the same package and pinout.
