Coaxial switches possess several notable characteristics that make them essential in various electronic applications.

High - Frequency Capability: Coaxial switches are designed to operate over a wide range of high - frequency bands, typically from low - MHz to several GHz or even higher. This enables them to handle radio - frequency (RF) and microwave signals effectively, meeting the requirements of modern communication systems, radar technologies, and satellite applications.

Low Insertion Loss: In the on - state, coaxial switches introduce minimal attenuation to the signal. The insertion loss is usually very low, often in the range of 0.1 dB to 0.5 dB. This ensures that the signal power is efficiently transmitted with little loss, maintaining the integrity and strength of the signal.

High Isolation: When in the off - state, coaxial switches provide excellent isolation between the signal paths. The isolation degree can reach 20 dB to 60 dB or more, effectively preventing signal leakage from one channel to another. This high isolation characteristic is crucial for reducing crosstalk and improving the overall signal - to - noise ratio of the system.

Fast Switching Speed: Coaxial switches can achieve rapid switching between different signal paths. The switching time is typically in the nanosecond (ns) to microsecond (μs) range. Some high - performance coaxial switches can even switch in as little as 10 ns to 100 ns. Such fast switching speeds allow them to respond quickly to changes in the signal, making them suitable for high - speed data processing and communication systems.

Good Repeatability: After multiple switching operations, coaxial switches maintain stable performance parameters. The consistency of their characteristics ensures reliable and accurate signal switching, reducing the need for frequent calibration and adjustment in practical applications. This makes them highly reliable and suitable for use in long - term and high - reliability systems
