SSP-94310-S1-B

Rev. 1.0

Description:
Model SSP-94310-S1-B is a W band ranging sensor module
based on FMCW radar principles. This sensor module isdesigned and manufactured for measurements of a moving or
stationary target's speed and distance. The sensor module hasa center frequency of 94 GHz and takes a nominal bias of +4.0
VDC/650 mA. The frequency modulation bandwidth of ±250
MHz is realized via a bias tuned Gunn oscillator. The
advantages of implementing bias tuned oscillator are the lower
cost and consistent frequency tuning linearity which are bothdesirable for volume production. The sensor module is configured with a bias tuned oscillator, anisolator, a directional coupler, a circulator and a balanced mixer. The directional coupler is used tosample the LO power to pump the mixer, and the circulator is used as a TX/RX diplexer. Various
antennas can be integrated with the module to form sensor heads for many system applications.

Caution:• Exceeding absolute maximum ratings shown will damage the device.
• The device is static sensitive. Always follow ESD rules when working with the device.
• Proper torque, 8.0 ± 0.4 inch-pounds (0.90 ± 0.02 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
• 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.
