The Mini-Circuits ZT-4X4B-18-S is a 4×4 blocking switch matrix operating from DC to 18 GHz, designed for RF test automation and signal routing. It features 8 SMA female ports mounted on a compact 3U height, 19-inch rack-mountable chassis. The matrix supports four simultaneous one-to-one switch paths with insertion loss up to 2.2 dB and isolation exceeding 80 dB across all frequency bands, and is bidirectional with a return loss of at least 18 dB. Control is available via USB HID or Ethernet using HTTP and Telnet protocols, with software support for Windows and Linux. The device specifies a cold switching RF input power of +33 dBm and hot switching of +20 dBm, with all RF ports capable of handling up to +30 dBm into internal terminations.
Mini-Circuits’ ZT-4X4B-18-S is a high-performance, 4 by 4 blocking switch matrix, operating over a wide bandwidth from DC to 18 GHz. The system is integrated into a compact, 3U height, 19-inch rack-mountable chassis with all RF ports (A1 to A4 and B1 to B4) on the front panel, all SMA female. The blocking configuration supports 4 active switch paths at any time, with each of the 4 “A” ports able to connect to any of the 4 “B” ports in a one-to-one arrangement. The matrix is bi-directional so the “A” and “B” ports can be used interchangeably as both inputs and outputs. The switch matrix can be controlled via USB or Ethernet (supporting HTTP and Telnet network protocols). Full software support includes our user-friendly GUI application for Windows and a full API with programming instructions for Windows and Linux environments.
