Dolph Microwave manufactures a high quality line of waveguide 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.

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.
In microwave solutions, phase shifters are passive microwave devices that change the phase angle of an RF signal. RF waves can combine to boost or attenuate the signal, depending on whether the waves are the same or different. The same frequency boosts the signal, while the opposite frequency attenuates it.
A phase shifter works by taking an input signal and adding a very small amount of delay to it, then mixing it with the original (non-delayed) signal so that certain frequencies of the audio are in or out of phase with each other. The time delay is modulated so the amount of delay varies with time.
