5g antenna switch mobile manufacturers

Antenna switches are vital for seamless signal transmission in 5G mobile phones. They enable efficient frequency switching, ensuring optimal network performance. This guide highlights the top manufacturers producing advanced 5G antenna switches for 5G/LTE mobile applications.

What is an Antenna Switch?

Reconfigurable antennas are mainly designed based on four parameters: frequency, bandwidth, radiation pattern, and polarization. Based on these, there are different reconfigurable antenna types. Switches are used between antennas and filters/duplexers/multiplexers for aperture and impedance tuning purposes.

Switches are made using different techniques such as RF MEMS, varactor diodes, and PIN diodes. Optically activated switches are used in fiber optic systems. RF MEMS switches offer speeds ranging from 1 to 200 µs.

Antennas with varactor diodes and capacitance can be controlled using varying bias voltage, offering a wide tuning range. PIN diode-based switches are used for fast switching (1 to 100 nsec) and fast dynamic reconfiguration designs.
