RFMW announced design and sales support for surface mount bias-tees from Marki Microwave. 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 30 V. Optional bypass capacitors can be added near the DC input port to filter noise on the DC line. With 1 W power handling, common BT-0035SMG-2 applications include amplifier biasing, diode biasing and DC level shifting. Available in a compact 0.150” x 0.220” package.
