Introduction

The TS63421K is a reflective open Single Pole Four Throw (SP4T) switch designed for antenna or filter tuning applications where high RF peak voltage handling is desired. TS63421K is suitable for frequency range from 1MHz to 1GHz. The TS63421K has a very low 1.9Ω on resistance and off capacitance of 0.35pF. This switch can select up to 16 independent states. The internal charge pump has also been disabled to eliminate the charge pump spurs. A -18V supply is needed on the Vcp pin. The TS63421K is packaged in a compact Quad Flat No lead (QFN) 3x3mm 16 leads plastic package.
