5G smartphones have at least 4 antennas. Some of these antennas will be used to transmit and receive while others are receive only. In case the transmitting antenna is blocked (by a hand or head), the smartphone will swap the transmit signal with a transfer switch to an antenna which is not blocked. This antenna swapping architecture has proven very effective, however the antenna transfer switch creates loss in the signal path. This loss grows with impedance mismatch and temperature.
Cavendish Kinetics RF MEMS Transfer Switches are the lowest loss switches in the industry. RF MEMS is also relatively insensitive to temperature and impedance mismatch. This yields maximum RF performance in any condition.
Cavendish Kinetics Transfer Switches also support the most challenging Carrier Aggregation band combinations with unparalleled linearity.
