LNA targets applications in the 1.5 to 8-GHz band

San Jose, Calif.—Aimed at a wide range of wireless mobile communications applications, Avago Technologies has developed a fully integrated GaAs low-noise amplifier MMIC for use in the 1.5 to 8 GHz band.

Avago's miniature MGA-21108 measures 2.5 by 2.5 by 0.55mm in an 8-pin STSLP package, Operating at supply voltages ranging from 1.4 to 3.3V, the this MGA-21108 is intended for use in low power or battery-operated applications and targets designers of mobile applications such GPS, WiFi, WiMAX, and UWB.

The MGA-21108 offers a very low noise figure of 1.5 to 2.8 dB at 1.5 to 8 GHz and high linearity performance of 18.7 to 10.7 dB at 1.5 to 8 GHz, which helps to significantly improve the sensitivity and dynamic range of the mobile receivers. Low power operation is at 18mA nominal current.

Broadband performance of Avago's MGA-21108 is achieved with only one external input matching component, and the power supply chokes and coupling capacitors are integrated into the device. Additionally, the MGA-21108 includes a CMOS-compatible shutdown pin that can also be used as a variable gain bias pin.

Pricing: Starts from $0.99 in 10,000 unit volumes.
Availability: Now.
