SKD-7538533025-1212-R1

Rev. 1.2

Description:
Model SKD-7538533025-1212-R1 a PIN diode based, single
pole, double throw (SPDT) switch with a TTL driver that
operates from 75 to 85 GHz. This model has an insertion
loss of 3.0 dB typical and an isolation of 25 dB nominal atits center frequency. The SPDT switch features WR-12
waveguides with UG-387/U anti-cocking flanges at the RF
input and output and a female SMA connector for TTL
control on the driver. The switch can be modified forvarious operational frequencies under different model
numbers.

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.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.
Other mechanical configurations are available under different model number.

Caution:•••••Exceeding absolute maximum ratings shown will damage the device.
The device is static sensitive. Always follow ESD rules when working with the device.
Any foreign objects in the waveguide will cause performance degradation and possible device
damage.
The case temperature of the device shall never exceed +50˚C. Use proper heatsink or fan ifnecessary.
Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.02 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
