The Keysight U3045AM12 is a 12-port mechanical test set operating from 10 MHz to 50 GHz, designed to expand 4-port network analyzer capabilities into full 16-port crossbar measurement systems. It delivers low-loss mechanical RF switching with exceptional isolation—crosstalk below −110 dB from 500 MHz onwards—and precise tracking performance across its frequency range. Typical reflection tracking at 40–50 GHz reaches ±(0.027 + 0.4/°C), while transmission tracking achieves ±(0.200 + 0.4/°C). The test set features 12 × 2.4 mm male connectors, rated for +25 dBm at test ports and +15 dBm at source and access ports. With directivity of 36 dB and source/load match specifications of 31 dB and 35 dB respectively at the top frequency band, the U3045AM12 enables accurate multiport device characterization across telecommunications, aerospace, and research applications.
