The one-slot
OSP-B102 (order no. 1505.5201.02) consists of 2
electromechanical SP6T relays, frequency range DC to 18
GHz, with non-termi-
nated SMA (female) connectors.

connectors.
The relays operate independently from each other. The terminal port is labeled with C
(common), the other relay ports are labeled with numbers.
The relay type is monostable (or "failsafe open"). Hence, with no voltage applied to a
relay, no RF connection is provided from terminal C to any of the numbered ports. To
establish an RF connection between C and one of the numbered ports, a continuous
voltage must be applied to the corresponding power terminal of the relay.
The relays are mounted directly into the module's panel and soldered to the module's
printed board, to avoid relay cabling and allow a compact module size.
The switch unit provides power supply and control via a single module bus cable to a
module bus connector on the module's printed board. The module's on-board memory
stores its configuration data.
