Skyworks White Paper
Ultra Low Noise Amplifiers
By Stephen Moreschi and Jody Skeen
 

This white paper describes the performance and characteristics of two new ultra low noise LNAs from Skyworks. Topics include techniques used in biasing and matching these devices. A circuit description, including information on thermal considerations, is also provided.

The SKY67150-396LF and SKY67153-396LF were designed to cover a wide bandwidth with the use of two separate devices with their design and performance analyzed from 30 MHz – 4.0 GHz. Package pin-outs for each device are identical, with the only differences in the applications schematic and frequency band of interest for each device. The remainder of the paper will primarily focus on the SKY67150-396LF but will also be applicable, unless otherwise noted, for the SKY67153-396LF.
