Measuring 2.5 by 2.5 by 0.55 mm in an eight-pin STSLP package, the MGA-21108 monolithic microwave IC (MMIC) from Avago Technologies targets use in the 1.5- to 8-GHz band. This fully integrated gallium-arsenide (GaAs) low-noise amplifier operates from supply voltages ranging from 1.4 to 3.3 V, suiting it for low-power and battery-operated applications like GPS, Wi-Fi, WiMAX, and Ultra-Wideband (UWB).

According to the company, the MGA-21108 offers a very low noise figure and high linearity performance, which helps to significantly improve the sensitivity and dynamic range of mobile receivers. This fully matched LNA module also will help developers of wireless handsets and other handheld communications devices simplify and reduce the size of their designs as well as reduce time-to-market.

The MGA-21109 achieves its broadband performance with only one input matching component. It also integrates the power-supply chokes and coupling capacitors. Its CMOS-compatible shutdown pin can be used as a variable gain bias pin. Furthermore, it offers broadband gain with 1.4 to 3.3 V, single supply, and high gain of 18.7 to 10.7 dB at 1.5 to 8 GHz. Its noise ranges from 1.5 to 2.8 dB at 1.5 to 8 GHz. And, it operates with an 18-mA nominal current.
