What is Noise Figure and How to Improve it with a Low Noise Amplifier

By |2018-07-16T19:58:42+00:00July 16th, 2018|Product Development|

Noise Figure (NF) describes the amount of noise a component, amplifier, or an entire radio receive chain contributes to the RF signal being received. Electrical noise is combined with the RF signal as it is generated by the RF transmitter and propagated through space. This signal is then captured by the receiving antenna and guided [...]

NuWaves’ Recent Filter Development That Addresses Today’s Biggest Issue and Bottleneck in GPS Satellite Communications

By |2018-07-13T20:19:55+00:00July 13th, 2018|Design Innovation|

NuWaves recently finished development on a high-powered triplexer to support GPS-III communication services. NuWaves’ triplexer is a unique and advanced piece of hardware that serves a specific purpose in satellite communications. GPS operating frequencies have the unfortunate fate of residing in a narrow range of frequencies that induce an effect known as multipaction. Multipaction is [...]

A Closer Look at Popular COTS RF Subsystem Hardware in 2018

By |2018-02-27T14:25:49+00:00February 14th, 2018|Design Innovation|

The increasing availability of COTS RF modules and subsystem components has made it convenient to design and assemble a custom high-performance RF communications system from off-the-shelf parts. However, while availability and selection has increased, top-of-the-line performance is still expensive. Being familiar with each category of RF subsystem modules and the various roles these modules play [...]
