SSK-SP923963-10-D1

Rev 1.1

Description:
Model SSK-SP923963-10-D1 is a W band ranging
sensor module that is designed and manufactured for
medium range measurements of a moving target'sspeed, distance and direction. The sensor module hasan operating frequency range of 91.5 to 96.5 GHz andtakes a nominal bias of +8.0 VDC/1,050 mA. The
sensor module is configured with a varactor tuned oscillator, an isolator, an amplifier, a power divider, acirculator and a I-Q mixer. The power divider is used to sample the LO power to pump the mixer, andthe circulator is used as a TX/RX diplexer. The varactor has tuning voltage range of 2.8 VDC to +30 VDC andprovides ±2.5 GHz tuning bandwidth. Various antennas can be integrated with the module to formsensor heads for many system applications.

All data presented is collected from a sample lot. Actual data may vary unit to unit slightly.
All testing as performed under +25˚C case temperature.
Other mechanical configurations are available under different model numbers.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

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 possibly damage
the device.
• The case temperature of the device shall never exceed +50˚C. Use a proper heatsink or fan ifnecessary.
• Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
