Multi-tasking LNA from MACOM

Ultra-small packaged amplifier is ideal for space constrained customers looking for frequency cov erage up to 6 GHz
M/A-COM Technology Solutions (MACOM) has introduced a low noise, high gain amplifier for wireless infrastructure, WiFi and L- and S- band applications. The MAAL-011078 is a low noise amplifier that it is claimed to offer an ultra-low noise figure and high gain from a single stage. The Low Noise Amplifier (LNA) covers a bandwidth between 700MHz and 6GHz with good noise figure, OIP3 and gain. The return loss can be optimised over narrow bands by implementing simple external matching networks.  The integrated active bias circuit allows direct connection to 3V or 5V voltage supply and minimises variations over temperature and process.  The bias circuit voltage supply (VBIAS) can be utilized as an enable pin to power the device up and down during operation. “This LNA is a designed as a second generation of MAAL-011076 and MAAL-011075.  It is designed using very low noise process and has more gain and bandwidth than any other LNA in the market,” says Amer Droubi, Product Manager, MACOM. “Matching is done externally in order to enable customers to make the necessary compromise between return loss, gain, OIP and noise figure.” The table below outlines typical performance:
