The mechanical switch matrix line covers DC up to 67 GHz. Benchtop modules span from low-frequency 75-ohm units (the RCM-3SPDT-75F, DCā2.15 GHz) all the way to the RCMX-2SP6T-E67, a latching SP6T covering DCā67 GHz. The RCMX “E” series fills the millimeter-wave range with models at 32.5, 42.5, 52.5, and 67 GHz, while rack-mount systems reach up to 40 GHz. This lets you match a routing solution to almost any test band, from HF through E-band.
The RCMX-2SP6T-E67 is the highest-frequency module in the catalog ā a terminated SP6T latching switch covering DCā67 GHz, with 1.5 dB typical insertion loss, 70 dB typical isolation, and 1 W power handling. For applications just below that, the RCMX-2SP4T-E53 reaches 52.5 GHz and the RCMX-2SP8T-E43 reaches 42.5 GHz. These extended-frequency modules are designed for millimeter-wave test setups such as 5G mmWave, radar, and satellite work.
The RC-2MTS-12N leads on power handling at up to 50 W ā a DPDT transfer switch covering DCā12.4 GHz with just 0.25 dB typical insertion loss and 80 dB isolation. For higher frequencies, several SPDT modules handle up to 40 W (the RC-1SPDT-A18, RC-2SPDT-A18, RC-4SPDT-A18, and RC-8SPDT-A18, all DCā18 GHz), and the RC-8SPDT-A26 handles up to 30 W at DCā26.5 GHz. Higher-frequency millimeter-wave modules trade power for bandwidth, typically handling 1ā5 W.
The catalog covers SPDT, SP4T, SP6T, SP8T, SP12T, and DPDT transfer (MTS) configurations, including latching and 75-ohm variants. The highest single-switch throw count in the benchtop range is SP12T ā the RCM-1SP12T-18 and RCM-2SP12T-18 (DCā18 GHz). SP8T options span DCā12 GHz up to DCā42.5 GHz, and transfer switches are available with two or three switches per unit (up to the RC-3MTS series). This breadth means most routing topologies can be built from stock.
Benchtop modules hold anywhere from one to eight switches in a single housing. For example, the RC-8SPDT-A18 packs eight SPDT switches (DCā18 GHz, 40 W each) into one unit, and the RC-8SPDT-50 provides eight SPDT switches up to 50 GHz. Multi-switch modules let you route several independent signal paths from one compact, software-controlled box rather than stacking separate units.
Yes. While most modules use USB and Ethernet control, the ZK series offers direct TTL control for integration into hardware-driven test systems ā including the ZK-MSP2TA-18 (SPDT, DCā18 GHz), ZK-MSP4TA-18 (SP4T, DCā18 GHz, 95 dB isolation), ZK-MSP6TA-12 (SP6T), and ZK-MSP8TA-12 (SP8T, DCā12 GHz, 100 dB isolation). Among the rack systems, the ZT-375-TTL also provides TTL control. TTL is useful when you want the switch driven by digital logic lines rather than a software interface.
Yes. The RCM-3SPDT-75F is a 75-ohm terminated SPDT module with three switches, covering DCā2.15 GHz with 70 dB typical isolation. Most RF switches are 50-ohm, so this 75-ohm option is specifically suited to video, CATV, and broadcast signal-routing applications where 75-ohm impedance is the standard. MCDI can advise if your test setup requires 75-ohm matching throughout.
The rack-mount range builds very high port-count switches from multiple elements. The ZT-315 implements a single SP40T switch (DCā18 GHz, 3U), the ZT-166 implements an SP32T (DCā18 GHz, 4U), and the ZT-SP36T-12A implements an SP36T (DCā12 GHz, 4U). At millimeter-wave, the ZT-14SP6T-40 provides two SP36T switch functions up to 40 GHz in a 6U chassis. For high switch counts, the ZT-310 holds 32 DPDT switches and the ZTM2-24SPDT-18 holds 24 SPDT switches.
Rack systems range from 1U to 6U and offer SMA, 2.92 mm, and N-type connectors. Compact 1U options include the ZTRC-4SPDT-A18 and ZTRC-4SPDT-A26 (SMA) and the ZT-317, which uniquely uses rear-panel N-type connectors up to 18 GHz. The 40 GHz millimeter-wave systems ā such as the ZT-14SP6T-40, ZTM2-8SP8T-40, and ZT-6SP6T-40 ā use precision 2.92 mm connectors. Connector grade is matched to frequency to preserve signal integrity at higher bands.
Yes. For large arrays, the ZT-310 (32 DPDT switches) and the ZT-16SPDT-A18 (16 SPDT switches) support USB, LAN, and daisy-chain control, letting multiple units be linked and managed over a single connection. For applications needing power redundancy, the ZT-2SP6T-12DPS is built with a dual power supply. These features support large, always-on automated test racks where reliability and simplified control matter. MCDI’s engineers can help configure the right system for your setup.
