Avago’s base station LNAs improve picocell, femtocell receiver sensitivity

Avago Technologies' ultra compact MGA-12516, 13516 and 14516 base station MMIC low noise amplifiers (LNAs) achieve very low noise figures and high gain performance at very low current consumption levels.

They are ideal for a wide range of cellular (GSM, CDMA, WCDMA, CMA2000 and TD-SCDMA) and WiMAX infrastructure applications, including picocell and femtocell base stations.

The MGA-12516, 13516 and 14516 LNAs are housed in a miniature 4.0 x 4.0 x 0.85 mm 16-pin quad-flat-non-lead (QFN) package. Avago's MGA-12516 is a matched-pair balanced LNA designed to operate between 800 MHz to 3 GHz. At 4V and 50 mA per LNA, the MGA-12516 delivers exceptional performance with a 0.62 dB noise figure, 23.8 dB gain, 33.5 dBm OIP3 and 17.9 dBm P1dB at 1.95 GHz.

Avago's MGA-13516 and MGA-14516 are two-stage LNAs with built-in active bias circuitry and the ability to adjust the supply current and gain through external matching without affecting the noise figure.

MGA-13516 is ideal for 400 MHZ to 1.5 GHz, while the MGA-14516 is designed for 1.4 GHz to 2.7 GHz frequencies. At 5V, 155 mA, Avago's MGA-13516 achieves an impressive 0.66 dB noise figure, 31 dB gain, 38 dBm OIP3 and 24 dBm P1dB at 900 MHz. The MeGA-14516 delivers a 0.68 dB noise figure, 33dB gain, 38 dBm OPI3 and 24 dBm P1dB at 1.95 GHz.

Avago's MGA-12516, 13516 and 14516 are available now. In 1,000 quantities, pricing for the MGA-12516, MGA-13516 and MGA-14516 begin at $3.44.
