BÖBLINGEN, GERMANY — Avago Technologies has announced a new family of MMIC low noise amplifiers (LNAs) designed for cellular and WiMAX infrastructure applications. The company's ultra compact MGA-12516, 13516 and 14516 base station LNAs achieve low noise figures and high gain performance at low current consumption levels. These LNAs 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. The 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.
The MGA-13516 and MGA-14516 are two-stage LNAs with built-in active bias circuity 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, the 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.
