Low-noise amplifiers

3 August 2011 Telecoms, Datacoms, Wireless, IoT

M/A-COM Technology Solutions has rolled out a new family of low-noise amplifiers (LNAs) for cellular infrastructure applications. The devices facilitate easy implementation in multiple RF and microwave front-end circuits including GSM, CDMA, WCDMA and LTE base stations and repeaters. The GaAs-based amplifiers meet the performance requirements of telecommunications equipment manufacturers optimising for minimum system noise figure and high receiver sensitivity.

The MAAL-010705 and MAAL-010706 are highly linear LNAs with low-noise figure, high-gain and excellent input and output return loss designed for operation from 0,5 to 1,6 GHz and 1,4 to 4,0 GHz respectively. These two amplifiers share the same pinout and are packaged in a RoHS compliant leadless 2 x 2 mm DFN package. The bias current and gain can be set with external resistors, allowing the user to customise the current consumption and gain value to fit the application.

The MAAL-010704 is a versatile broadband LNA which operates in the frequency range from 0,1 to 3,5 GHz and is packaged in an SOT-363. Its bias current can also be set externally via a resistor.

The LNAs all feature an integrated active bias circuit allowing direct connection to a 3 V voltage supply while minimising variation over temperature and process.
