Manual Phase Shifter, DC~8GHz, 50W, SMA

A manual phase shifter is a device that changes the phase transmission characteristics of a signal through manual mechanical adjustment. Its core function is to precisely control the phase delay of microwave signals in the transmission path. Unlike electronic phase shifters that require power and control circuits, manual phase shifters are known for their passive, high-power capacity, distortion free, and excellent cost-effectiveness, and are commonly used for laboratory debugging and system calibration. The following briefly introduces its characteristics and applications:

Characteristics:

1. Ultra wideband coverage (DC-8GHz): This feature makes it a truly versatile tool. It can not only easily cope with common mobile communication (such as 5G NR), Wi-Fi 6E and other frequency bands, but also cover down to the baseband (DC), touch up to the C-band and even some X-band applications, meeting a wide range of phase adjustment needs from DC bias to high-frequency microwave signals.
2. Excellent phase accuracy (45°/GHz): This indicator means that for every 1GHz increase in signal frequency, the phase shifter can provide precise 45 degree phase changes. Within the entire 8GHz bandwidth, users can achieve precise, linear phase adjustment of over 360°. This high precision is crucial for applications that require fine phase matching, such as calibration of phased array antennas and beamforming simulations.
3. High reliability SMA interface: Using SMA female head, it ensures seamless and stable connection with the vast majority of test cables (usually SMA male head) and equipment on the market. The SMA interface has stable performance in the frequency band below 8GHz and good repeatability, ensuring the connection reliability and signal integrity of the testing system.
4. Excellent performance indicators: In addition to phase accuracy, such products typically have low insertion loss and excellent voltage standing wave ratio (VSWR), ensuring that the impact on signal strength and quality is minimized while adjusting the phase.

Applications:

1. Research and laboratory testing: During the prototype development phase, it is used to simulate the system behavior of signals under different phase differences and verify algorithm performance.
2. Phased array system calibration: Provides repeatable and accurate phase reference for channel calibration of phased array antenna units.
3. Teaching and demonstration: Vividly demonstrating the concept and role of phase in microwave engineering is an ideal teaching tool for communication laboratories.
4. Interference and cancellation simulation: By precisely controlling the phase, interference scenarios can be constructed or the performance of cancellation systems can be tested.
