SK8-0524036550-KFKF-AD1

Rev. 1.2

Description:
Model SK8-0524036550-KFKF-AD1 is an absorptive PIN diodebased, single pole, eight throw switch with a TTL driver that
operates between 0.5 and 40 GHz. The switch requires a separate 5 V and +5 V biasing in addition to the TTL control. This modeloffers a small form factor, typical 6.5 dB insertion loss, and 50 dB
minimum isolation with a switching speed up to 50 nanoseconds.
The switch has female K connectors for all RF ports and solder pinsfor bias port and TTL control.

SP8T PIN Switch with TTL Driver, Absorptive, 0.5 to 40 GHzNote:•••••All data presented is collected from a sample lot. Actual data may vary unit to unit slightly.

All testing was performed under +25 ˚C case temperature.
TTL is commonly defined 0 to +0.8 Volt as “TTL Low” and +3.3 to +5.0 Volts as “TTL High”.
Other mechanical configurations are available under different model numbers.
Eravant reserves the right to change the information presented without notice.

Caution:•••••Exceeding absolute maximum ratings shown will damage the device.
The control signal per the true table is needed all time to keep the switch under normal workingcondition. No control signal applied any time could cause excessive negative current, which may
damage the switch.
The device is static sensitive. Always follow ESD rules when working with the device.
Reversing polarity will destroy the device.
Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
