SSP-77323-D1

Advanced

Description:
Model SSP-77323-D1 is an E band ranging sensor
module that is designed and manufactured for medium
range measurements of a moving target's speed, travel
direction and distance. The sensor module has an
operating frequency range of 76.25 to 76.75 GHz andtakes a nominal bias of +8.0 VDC/1,250 mA. The sensor
module is configured with a varactor tuned oscillator, anisolator, an amplifier, a directional coupler, a circulator,
and a balanced I/Q mixer. The directional coupler is used to sample the LO power to pump the mixer,
and the circulator is used as a TX/RX diplexer. The varactor has tuning voltage range of DC to +25 VDCand provides ±250 MHz 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.
Eravant 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. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
