Toshiba TCWA1225G SPDT RF antenna switch

Toshiba’s TCWA1225G is a high-power SPDT (single-pole double-throw) RF antenna switch that will be important for the expansion of 5G networks. This is because the expansion requires antennas that are increasingly composed of complex signal transmission paths.

Traditionally, RF switching is used for switching between complex transmission paths. However, the RF switch must have low insertion loss and high input power, and be small enough so that the number of RF switches and the size of antennas would not increase due to space limitations. The SPDT RF switch resolves both of those limitations, and should therefore be able to help accelerate 5G implementation.

The SPDT RF offers an input peak power of 46 dBm (at 8dB PAR) in a small footprint; this means that while antenna size can be maintained, or even reduced, power output can remain consistent. The switch was designed and produced in response to the increased introductions of massive MIMO (multiple input, multiple output) technology in telecommunications base stations, which use multiple transmit and receive antennas to provide ultra-high speed and ultra-large capacity radio communications services essential for 5G.
