SFD-144224-05SF-N1

Rev 1.0

Description:
Model SFD-144224-05SF-N1 is a G Band amplitude detector thatcan be used for full or narrow band applications. The detector iszero biased and intended for small signal detection purposes.
With a distinct circuitry design and careful diode selection, thedetector 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 anda 1 MΩ video output impedance. The minimum detectable signal
level is approximately -45 dBm.

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-144224-05SF-P1.
The amplitude detector is a small signal detector. The sensitivity shown is for RF signal -20 dBmor 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. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
