Description
The SHF BT110R bias tee is the RoHS compliant successor of the SHF BT110. It outputs the superpositionof the signals applied to the AC and to the DC port. Any existing DC content is blocked from its AC input
1
while the DC input is practically only allowing transmission of pure DC .
Based on SHF’s air line construction, it offers resonance-free transmission up to 110 GHz. In addition to thelow insertion loss, all products have an extremely low group delay ripple.

Applications


Optical Communications

High-Speed Pulse ExperimentsSatellite Communications



Research and Development

Antenna MeasurementsData Transmission

Configurations
A- AC port: 1.00 mm male, AC+DC port: 1.00 mm female

B- AC port: 1.00 mm female, AC+DC port: 1.00 mm male

C- AC port: 1.00 mm male, AC+DC port: 1.00 mm male

D- AC port: 1.00 mm female, AC+DC port: 1.00 mm femaleOne of above configurations has to be chosen. For more information, please be referred to the mechanicaldrawing on the last page of this data sheet. The DC-port is always SMA female.

Options
HV25- High Voltage (maximum DC voltage extended to 25 V)

1In case a low- and a high frequency signal should be combined a SHF Diplexer (essentially a bias tee with a certain bandwidth in thelow frequency path) would be the right choice.

230 dBm (1 W) equals 20 V peak to peak for continuous sinusoidal signals. A pulsed excitation with an average of 1 W and thus
having significantly higher peaks is possible.
The maximum RF input power does not change in case a signal is applied to the DC port.
