A PDMS valve-less micro pump structure includes a PDMS body having a contour surface, a membrane covering the contour surface of the PDMS body, and a PZT actuator located on the membrane. The switch fabric is operable to selectively couple any of a plurality of antennas to antenna signal paths based upon the digital data and the digital clock extracted from at least one of the antenna signal paths conducting RF signals. A calculation section 21 calculates using the amplitude signal and the quadrature data to output a discrete value having a level discrete at every predetermine time period, and first and second phase signals.
