Patent ID: 7924024

Claim:
A calibration module for use in calibrating a vector network analyzer (VNA), the calibration module comprising: a plurality of ports connectable to a VNA; a plurality of calibration standards; and a plurality of single pole multi throw (SPMT) switches each of which includes a single pole terminal, multiple throw terminals, a shunt terminal corresponding to each of the multiple throw terminals, and a switching path between each of the throw terminals and the single pole terminal, and between each of the shunt terminals and the single pole terminal, wherein each of the switching paths include at least one solid state switching element; wherein the calibration standards are selectively connectable to the ports of the calibration module by selectively controlling the switching elements of the switching paths of the SPMT switches; and wherein each port of the calibration module is connected to one of the throw terminals of one of the SPMT switches without any intervening pole terminal.
