RF Parameters

Learn more about parameters and metrics used to quantify performance of radiofrequency hardware. We've developed a series of articles to assist clients in building a more fundamental understanding of the technology behind wireless communications. Articles in this section provide an introduction to many of the complex topics associated with RF procurement.

Key Articles

Gain is often incorrectly used as a means of performance comparison between antennas, where the model with the highest gain figure represents the highest performance. As its alias suggests, gain ...
One of the key parameters of any radio transmission component is VSWR or Return Loss (RL), which both measure how well the component is matched to other system components. Both are used ...
The following article serves to build an understanding about the antenna parameter known as Polarisation. Polarisation is perhaps the most fundamental characteristic of an antenna which describes the ...
The following article serves to build an understanding about the antenna parameter known as Passive Intermodulation (PIM). PIM has recently become a critical parameter in component design due to new ...

The following article serves to build an understanding about the antenna parameter known as Electrical Tilt. Tilting antennas is an important concept for applications like cellular and multipoint base ...

The following article serves to build an understanding about the antenna parameter known as Maximum Input Power, Per Port. Defining an antennas maximum input power rating is important to ensure that, ...

The following article serves to build an understanding about the antenna parameter known as Inter-Port Isolation. The parameter, sometimes referred to as Port-to-Port Isolation, is a simple metric ...

The following article serves to build an understanding about the antenna parameter known as Front-to-Back Ratio (F/B Ratio). The objective of any directional transmission is to ensure the most amount ...
The following article serves to build an understanding about the antenna parameter known as Frequency Range. An antennas frequency range is one of its most fundamental characteristics, which describes ...
The following article serves to build an understanding about the antenna parameter known as cross polar isolation. Cross polar isolation is a metric specific to orthogonally polarised antennas, and ...
The following article serves to build an understanding about the antenna parameter known as Cross Polar Discrimination (XPD). Cross-polar discrimination is important for a low level of correlation ...
The following article serves to build an understanding about the antenna parameter known as Half Power Beamwidth (HPBW). Beamwidth is a simple metric used to describe the dominant direction of ...
