FAQs of Waveguide Diplexer
Definition of Waveguide Diplexer
It is a three-port network that splits the input signal from the common port into two paths based on frequency. Ensure that both receiving and transmitting can work normally at the same time. The simplest form of multiplexer is a duplexer, which divides a signal from a common port into many different paths.
Role of Waveguide Diplexer
A duplexer is a device that separates or combines high and low frequencies. Each duplexer has a low pass cutoff frequency, below which signals are routed from the common port to the low pass port, and a high pass cutoff frequency, above which signals are routed from the common port to the high pass port. It is a three-port passive (RF) filter component that shares a common antenna between two different frequency bands. This technology allows transmitters operating on different frequencies to use the same antenna, and each band can transmit and/or receive.

FAQs of Microwave Feedhorn
Definition of Microwave Feedhorn
Microwave feedhorn is a small horn antenna used to couple a waveguide to, for example, a parabolic dish or an offset dish used to receive or transmit microwaves. A typical application is the use of satellite dishes to receive satellite TV.
Work Principle of Microwave Feedhorn
Microwave feedhorn is basically a horn antenna that sits between the transceiver and the antenna reflector in a satellite antenna system. When a signal from a satellite is received, the signal is reflected from the parabolic antenna to the feed horn, where it is passed to a low noise block (LNB) where it is downconverted and further processed. The feed horn provides a certain level of gain and is designed to support a specific type of polarization so that it can filter out unwanted signals by allowing only certain polar waves based on the polarization of the horn antenna.

Waveguide phase shifter types
Dolph Microwave excels in waveguide technology, offering advanced solutions in the realm of RF waveguide phase shifters. The company distinguishes itself through its expertise in two fundamental types of waveguide phase shifters.
Analog Phase Shifters: Dolph's analog phase shifters utilize an analog signal, typically voltage, to alter the output phase of a signal. This technology enables continuous and precise control over phase adjustments, allowing for seamless modulation in various applications. The analog approach is particularly advantageous when fine-tuning phase shifts is critical for optimal performance in communication systems, radar applications, or other microwave-dependent technologies.
Digital Phase Shifters: In contrast, Dolph's digital phase shifters operate using a digital signal comprising two discrete stages. This method facilitates discrete phase adjustments in a step-wise fashion. Digital phase shifters are known for their reliability and accuracy, making them suitable for applications where discrete and quantized phase shifts are sufficient.
Dolph Microwave's commitment to providing a diverse range of waveguide phase shifter options, whether analog or digital, underscores its dedication to meeting the nuanced requirements of modern RF communication systems with cutting-edge technology.

Dolph has developed a comprehensive line of waveguide ortho-mode transducer covering C, X, Ku and Ka bands. The devices offer very high performance at a very competitive price. Orthomode Transducers separate a signal applied to the circular waveguide input port into its two linear orthogonal components at the rectangular waveguide output ports between the polarizations. In reverse, two orthogonal linearly polarized signals combine, producing an output in the circular waveguide port. The resulting polarization may be linear, circular, or elliptical depending on the relative phase and amplitude of the two orthogonal input signals. Please call us with your specification and discuss your needs with one of our sales engineers.
Note: Take Ka-Band Waveguide Ortho-Mode Transducer (OMT) as an example.
FAQs of OMT (Orthogonal Mode Transducer)
Definition of OMT (Orthogonal Mode Transducer)
An Orthogonal Mode Transducer (OMT) is a waveguide component commonly referred to as a polarization duplexer. Orthogonal mode transducers are used to combine or split two orthogonally polarized microwave signal paths. One of the paths forms the uplink and travels through the same waveguide as the receive signal path or downlink path.
Application of OMT (Orthogonal Mode Transducer)
Orthogonal mode transducers are used to combine or separate two orthogonally polarized microwave signal paths. One of the paths forms the uplink and travels through the same waveguide as the receive signal path or downlink path. Such equipment may be part of a Very Small Aperture Terminal (VSAT) antenna feed or a terrestrial microwave radio feed; for example, OMTs are often used with feed horns to isolate orthogonal polarizations of signals and transmit transmit and receive signals to different ports.

Industrial Microwave Tuners are waveguide components used to match the load impedance with the source impedance. They minimize the amount of reflected power, providing the most efficient coupling of power to the load. Dolph Microwave supplies both manual 3- and 4-stub tuners, electrical and auto tuners. Industrial Microwave Tuners utilize manual tuning and lock simply. They are generally used in applications where the load impedance varies significantly due to variations in the load. Microwave components for industry microwave is 915 and 2450MHz.
Taking the WR340 for example.
FAQs of Industrial Microwave Tuners
Application of Industrial Microwave Tuners
Industrial Microwave Tuners is a common impedance adjust. The depth, spacing and radius of the pins can be set as required. It is a common device for impedance matching in high-power microwave systems.
Work Principle of Industrial Microwave Tuners
When a metal pin of a certain diameter is inserted along the center of the broad side in the waveguide, its equivalent circuit is parallel susceptance. When the insertion depth of the pin is shallow, the pin mainly acts as a concentrated electric field, and the equivalent susceptance of the pin is capacitive. As the insertion depth of the pin increases, the capacitance increases, and at the same time, the axial current on the broad side of the waveguide flows along the axial direction of the pin, thereby generating a magnetic field and making the pin have a certain inductance. LC series loop on the main line. The resonance of the pin is related to the operating wavelength, insertion depth and width of the narrow side of the waveguide.
