Avago Technologies has a MMIC low noise amplifier (LNA) designed for mobile and WiMAX basestations where the supply current can be adjusted to optimise power consumption and gain.

The 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 designed for frequencies between 400MHz to 1.5GHz, while the MGA-14516 is designed for 1.4GHz to 2.7GHz frequencies.

At 5V, 155mA, the MGA-13516 achieves a 0.66dB noise figure, 31dB gain, 38dBm OIP3 and 24dBm P1dB at 900MHz. The MeGA-14516 delivers a 0.68dB noise figure, 33dB gain, 38dBm OPI3 and 24dBm P1dB at 1.95GHz.

As a result the devices will be used for GSM, CDMA, WCDMA, CMA2000 and TD-SCDMA and WiMAX infrastructure applications, including picocell and femtocell basestations.

The MGA-12516, 13516 and 14516 LNAs are housed in a miniature 4.0x4.0x0.85 mm 16-pin quad-flat-non-lead (QFN) package.
