MA/COM introduces GaAs based LNA for 22-38 GHz applications

The low noise figure, and high gain amplifier is suited to in receiver applications
M/A-COM Technology Solution has launched a new three-stage low noise amplifier for point to point applications.

The MAAL-011111 is a low noise amplifier covering 22 - 38GHz in a small and low cost 3 x 3 mm QFN package. It offers 19dB of gain and less than 3dB of noise figure.

The LNA is self-biased requiring only a single 3.3V voltage supply and there is no need for any external components. It is claimed to be easy to implement and takes up a small board area. The high gain and low noise figure makes it well suited as a first stage LNA in receiver applications covering multiple bands simultaneously.

"The MAAL-011111 offers excellent performance across the full band up to 38GHz in a small fully molded QFN package,” says Amer Droubi, Product Manager, MACOM. “The low noise amplifier has an integrated ESD protection and by-pass capacitors and requires a single positive bias supply, making it an idea low cost and easy to implement solution for a wide range of applications.”
