RF power divider

It splits an input signal into two identical signals called in-phase. In some cases, it is also used as a power combiner. When it is used as a power combiner, the common port is used as the output, and the equal power ports become the inputs. When uncorrelated signals need to power combined the insertion loss from equal power port to the other equal power port which is isolation is the important specification. The important specifications of a power divider are insertion loss, return loss and amplitude and phase balance between the arms. The application of this device is critical and therefore, the quality matters.

Waveguide To Coaxial Adapter

Electrical cables with three or more layers, an insulating layer containing a conductor material which is surrounded by tubular shields are the coaxial cables. Whereas, waveguides are the structures to guide and direct types of waves.

Electromagnetic waves of a particular frequency are propagated by using a waveguide component of a particular dimension. Sometimes integrated circuits also use waveguides.

A waveguide component fitting the waveguide tubing and ending with a flange and a coaxial probe assembly connection hardware and coaxial adapter is termed as a waveguide to coaxial adapter.

One wall of the waveguide adapter housing typically tapped the coaxial cable adapter.

Standard Gain Horn Antenna

Shaped like a pyramidal horn design these broadband passive devices direct a bean radio waves at an accurate frequency. These are also used as the calibration devices to measure the gain of other antennas.

Standard gain horn antenna has industrial and scientific applications. It is designed to measure, control, and generate high levels of electromagnetic Radio Frequency (RF) energy. That is why the amplifier used must always be connected to some appropriate load like antenna, receiver, or a field generating device.


It is important to operate the device at a location where radiated energy can be controlled to avoid injuries and violation of regulatory levels of electromagnetic interference. There are two ways of polarization; horizontal polarization and vertical polarization which is determined by the orientation of the RF connector.


If the RF connector is parallel to the ground, it means the antenna is in the horizontal polarization, and if the RF connector is perpendicular to the ground, it implies that the antenna is in the vertical polarization.


The standard gain horn antenna has a vast range of applications. The good radiation performance, simplicity, and versatility of the antenna make it ideal from gain comparison to the parabolic feeds. These are an ideal solution for compliance testing due to the 30-degree beam width and flat antenna response.

The 30-degree beam width also allows the optimal EUT coverage. These antennas are available with different beam width characteristics and gains. The good quality antennas even respond beyond their frequency ranges. The only power-limiting component on the antenna is waveguide to coaxial adapter, and even it can be removed when high fields are required.
