Manufacturers Antenna Switch for 5G mobile phones, LTE mobile antenna tuner switch

This page describes 5G NR Antenna switch and its specifications used in 5G and LTE. The manufacturers of 5G mobile phone Antenna Switch and LTE mobile antenna tuning switch are also mentioned.

What is Antenna switch ?

Reconfigurable antennas are mainly designed based on four parameters viz. 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 purpose. Switches are made using different techniques such as RF MEMS, Varactor diodes, PIN diodes etc. Optically activated switches are used in fiber optic systems.

RF MEMS switches offer speed in the range from 1 to 200 µs. > Antenna with varactor diode and capacitance can be controlled using varying bias voltage offer wide tuning range. PIN diode based switches are used for fast switching (1 to 100 nsec) and fast dynamic reconfiguration designs.
