M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) has launched a three-stage low-noise amplifier (LNA) covering frequencies of 22-38GHz for point-to-point (PtP) applications.
Housed in a small, low-cost 3mm x 3mm QFN package, the MAAL-011111 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. Input return loss is 10dB and output return loss is 13dB. The supply current is 55mA. The new device is easy to implement and takes up a small board area, says MACOM. The high gain and low noise figure makes it suitable 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 product manager Amer Droubi. "The low-noise amplifier has 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."
Production quantities and samples of MAAL-011111 are available from stock.
