SFD-503753-15SF-P1

Rev. 1.0

Description:
Model SFD-503753-15SF-P1 is a V Band amplitude detector
that can be used for full or narrow band applications. Thedetector is zero biased and intended for small signal detection
purposes. With a distinct circuitry design and careful diodeselection, the detector exhibits high sensitivity and extremely
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. Theminimum detectable signal level is approximately -50 dBm.

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. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
