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.
There are many microwave waveguide manufacturers, but we are one of the best choices for you.
Applications An Electromyography (EMG) use EMG electrodes to pick up the electromyographic signal directly from the skin surface or within the subjects muscle using disposable fine-wire electrodes. Both are typically expressed in SI units micro Volt (mv). The Bioforcen-TB0810 model Biomechanics EMG can be used for biomechanics, engineering, medical research, orthopedics, rehabilitation evaluation, prosthetics, and general industrial uses. Specific uses include gait analysis, testing or stability analysis, neurological analysis, prosthetics fitting, athletic performance, shoe design, and force, power, and work studies. Description The EMG signal from each muscle is individually pre-amplified, band-pass filtered prior to digitization, and then converted to a binary sample for each of the channels. These operations are all performed directly in the subject back-pack to maximize signal quality. The binary information is then sent from the subject back-pack unit, via a single lightweight cable or wireless, to the desktop unit where it checked for transmission accuracy and then converted to an analog signal suitable for almost any analog data recording system. The desktop unit provides full electrical safety isolation for the subject. AMPLIFICATION The Bioforcen-TB0810 model Biomechanics EMG provides excitation and amplification for multiple channels in one convenient package. These amplifiers process the transducer signals and provide outputs suitable for an A/D converter so that the data can be stored and processed by a computer. CALIBRATION Each platform is inspected and tested in JUNE calibration facility. The calibration procedure provides a detailed sensitivity matrix and a complete test of all system components, including the amplifier and the connecting cable if ordered together.
