RF Mechanical Switch (DC – 50GHz, Including One SPDT Mechanical Switch, 2.4mm Female)
In order to meet the multi-port test requirements of microwave and millimeter wave systems, SIGLENT has introduced the SSU5000A series of mechanical switches with frequency ranges up to 50GHz, depending on the model ordered. The SSU5000A has a compact design, excellent RF characteristics, low insertion loss, great impedance matching, and extraordinary short switching time.
Models with up to four independent mechanical switches are available. Switch-type options include single-pole double-throw and single-pole six-throw. SMA or 2.4mm connectors are employed depending on the model’s maximum frequency range. TTL control is supported.
Several versions available
Several models of the SSU5000A series mechanical switches are available with different frequency ranges, switch counts, switch types, and connectors. Please see the table below for an overview.
