Dolph Microwave manufactures a high quality line of microwave phase shifter, which is utilize hybrid design, making it ideal for high power and low loss. The phase shift is approximately linear with dial rotation, but not frequency. which can change the phase of the signal in the waveguide transmission system within the range of 0 to 360�°. Please call us with your specification and discuss your needs with one of our sales engineers. Note: Take an example of WR112 High Power Waveguide Phase Shifters 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 microwave antenna feed horn covering C, X, Ku and Ka bands. The devices in these assemblies are precision machined from aluminum or copper and offer very high performance at a very competitive price. Each device is tuned to meet exacting electrical specifications. Additionally, entire feeds are assembled and tuned as a whole to provide superior performance compared to individually assembled components that are not tuned as a unit. Dolph can provide either complete feeds or standalone devices. Please call us with your specification and discuss your needs with one of our sales engineers. Note: Take C-Band Offset Feedhorns as an example. 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. There are many microwave waveguide manufacturers, but we are one of the best choices for you.
Waveguide diplexers is used to send and receive channel design for the device, it can ensure sending and receiving frequency loss, also can ensure the isolation between the sending and receiving channel. For more product information, please call us and discuss with one of our sales engineers. 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. Other antenna feeds with high quality and wide applications. There are many microwave waveguide manufacturers, but we are one of the best choices for you.
