5G technology brings faster data speeds, lower latency, and greater capacity to modern communications. To enhance signal coverage, 5G extenders, signal boosters, or repeaters are used in areas with poor signal quality, especially in indoor and remote areas. When selecting a 5G extender, it is necess... read more

Filters are devices used in electronic circuits to select specific frequency ranges. Low-pass filters allow signals below a cutoff frequency to pass through, while high-pass filters allow signals above the cutoff frequency to pass through. Band Pass Filters allow only frequencies within a specific r... read more

Crystal oscillators play a pivotal role in measurement equipment, providing critical support with their highly stable and precise frequency signals. From precise timing in GPS/GNSS receivers to angle and distance measurement in total stations, to height measurement in digital levels and signal proce... read more

Sound waves and light waves differ significantly in their frequencies and nature. Sound waves are mechanical waves with frequencies typically within the audible range for humans, while light waves are electromagnetic waves with much higher frequencies. Crystal oscillators can generate frequencies us... read more

A mixer is an RF (radio frequency) component that combines two or more input signals to produce an output signal containing new frequencies, typically the sums and differences of the original frequencies. The core of a mixer is nonlinear components such as diodes or transistors, which enable the con... read more
