SFD-753114-103-10SF-N1

Rev 1.1

Description:
Model SFD-753114-103-10SF-N1 is a W Band amplitudedetector that can be used for full or narrow band applications.
The detector is zero biased and intended for small signal
detection purposes. With a distinct circuitry design and careful
diode selection, the detector exhibits high sensitivity andextremely flat output characteristics across the full waveguide
operating bandwidth. The detector is designed to have a 10
MHz video bandwidth and a 1 MΩ video output impedance.
The minimum detectable signal level is approximately -50 dBm.

Note:• All data presented is collected from a sample lot. Actual data may vary unit to unit.
• All testing was performed under +25˚C case temperature.
• The positive output voltage polarity is offered under the model number SFD-753114-103-10SFP1.
• The amplitude detector is a small signal detector. The sensitivity shown is for RF signal -20 dBm
or lower.
• Eravant reserves the right to change the information presented without notice.
Caution:••••Exceeding absolute maximum ratings 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 can possibly
damage the device.
Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
