Low noise, high gain amplifier for multi-market applications

The return loss can be optimised over narrow bands by implementing simple external matching networks. The integrated active bias circuit allows direct connection to 3 or 5V voltage supply and minimises variations over temperature and process. The bias circuit voltage supply (VBIAS) can be utilised as an enable pin to power the device up and down during operation.

“This LNA is 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,” said 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.”
