Fairview Microwave's Noise Figure - Noise Temperature Calculator will produce either noise figure or noise temperature, depending on the input type.

Noise figure (NF) measures of degradation of the signal-to-noise ratio (SNR), caused by components, such as amplifiers, in an RF signal chain. The noise figure number, displayed in decibels (dB), represents the performance by which an amplifier or RF receiver can be measured.

Noise temperature is a representation of noise in terms of the temperature required to produce an equivalent amount of Johnson-Nyquist Noise.

A TNC (Threaded Neill–Concelman) connector is a threaded version of the standard BNC connector, designed to deliver better performance at higher frequencies. Instead of the bayonet-style lock used on BNC, the TNC uses a secure screw-on coupling mechanism, which creates a more stable connection and reduces signal leakage especially in environments with vibration or movement. Inside, the connector uses a standard 50-ohm impedance and supports frequencies typically up to 11 GHz or higher, depending on the specific design. Because of the threaded mechanism, TNC connectors maintain consistent electrical contact and lower VSWR across wider bandwidths, making them reliable for precision RF systems.

As millimeter-wave technology expands into applications like 5G, automotive radar, WiGig and advanced imaging, the demands placed on test setups are changing, too.

At these frequencies, the interconnect itself matters. Connector geometry, cable loss, waveguide characteristics, transitions and even mechanical factors like bending can influence measurement performance.

Our technical article, “An Introduction to Passive Interconnect for Millimeter-Wave Test,” explores the fundamentals engineers should consider when working with mmWave test systems, including:

+ Coaxial transmission lines and high-frequency connectors
+ Waveguide propagation and loss considerations
+ Coax-to-waveguide and planar transitions
+ Factors that can impact insertion loss, VSWR and measurement integrity

Whether you’re working with radar, 5G or other high-frequency applications, understanding the interconnect is an important part of building a reliable test setup.

Skin Depth refers to how deeply an RF signal can pe*****te a material, which is dependent on the frequency as well as the material's properties. Fairview Microwave's Skin Depth Calculator returns skin-depth as a function of a material's resistivity and permeability, as well as the application frequency.

Most engineers think of noise as something to eliminate. But what if it's one of your most valuable test tools?

This technical article explores how Zener diode noise sources generate controlled Additive White Gaussian Noise (AWGN) and why they've remained essential for RF and microwave testing for decades. Learn how these deceptively simple devices enable accurate measurements of receiver performance, noise figure and system behavior.

If you work in RF design, test or validation, this is a worthwhile read.
