The PE42543 is an absorptive SP4T RF switch designed for use in test/ATE, microwave and other wireless applications. This broadband general purpose switch is a pin-compatible version of the PE42542 with faster switching time and settling time. It exhibits low insertion loss, high isolation and linearity performance from 9 kHz through 18 GHz. No blocking capacitors are required if DC voltage is not present on the RF ports.
