Surface-mount bias-tees operate from 20 MHz to 35 Ghz
Surface-mount bias-tees from Marki Microwave are in stock at distributor RFMW.
The BT-0035SMG-2 bias-tee uses a proprietary wire-wound coil for ultra-broadband, resonance-free operation from 20 MHz to 35 GHz.
DC current is 500 mA from a maximum DC voltage of 30V. Optional bypass capacitors can be added near the DC input port to filter noise on the DC line.
With 1 Watt power handling, common BT-0035SMG-2 applications include amplifier biasing, diode biasing and DC level shifting. Available in a compact .150” x .220” package.
