The TS63421K from Tagore Technology is an SP4T Antenna/Filter Tuning Switch from 1 MHz to 1 GHz. The switch is based on GaN-on-Si Technology. It has a switching time of 2 µs and provides more than 20 dB of isolation. This switch can handle a peak RF voltage of 100 V and has an insertion loss of less than 0.6 dB. It has a very low ON resistance of 1.9 ? and an OFF capacitance of 0.35 pF. The switch supports 16 possible independent state configurations and allows each state to be controlled independently. It requires a DC supply from 2.5 to 5.5 V and a DC digital control voltage from 1.2 to 5.0 V. The TS63421K is available in a 16-lead QFN package that measures 3.0 x 3.0 x 0.8 mm and is suitable for use in dynamic matching, private mobile & public safety radio handsets, cellular infrastructure, and satellite terminal applications.
