CRS-33S

Commercial Failsafe 2P3T, DC-18GHz

Elite Failsafe 2P3T, DC-18GHz

The CCRS-33S/CRS-33S is a broadband, 2P3T, electromechanical coaxial switch designed to switch a

microwave signal from a common input to either of two outputs. The characteristic

impedance is 50 Ohms. The switches are small with the minimum spacing that is compatible with SMA

connectors, and can also be used as a SPDT switch with external terminations.

The resistance of the actuator coil varies as a function of

temperature. There is an inverse relationship between the

Where:

Failsafe

A failsafe switch reverts to the default or failsafe position

when actuating voltage is removed. This is realized by a

return spring within the drive mechanism. This type of switch

requires the continuous application of operating voltage to

select and hold any position. (Multi-position switches are

normally open with no voltage applied).

speciﬁed, the maximum indicator contact rating is 30 Vdc,

50 mA, or 1.5 Watts into a resistive load.

Isolation

Isolation is the measure of the power level at the output

connector of an unconnected RF channel as referenced to

the power at the input connector. It is speciﬁed in dB below

the input power level.

Switching Time

Switching time is the total interval beginning with the arrival

of the leading edge of the command pulse at the switch DC

input and ending with the completion of the switch transfer,

including contact bounce. It consists of three parts: (1)

inductive delay in the coil, (2) transfer time of the physical

movement of the contacts, and (3) the bounce time of the

RF contacts.

TTL Switch Driver Option

As a special option, switch drivers can be provided for both

failsafe and latching switches, which are compatible with

industry-standard low-power Schottky TTL circuits.
