The BTL-0035SMG from Marki Microwave is a Miniature Bias Tee that operates from 500 kHz to 35 GHz. It can withstand a DC voltage of up to 30 V and 500 mA of current. The bias tee is built using Marki Microwave’s proprietary wire-wound coil technology and is available in single/dual-port configurations. It can handle up to 1 W of power, has an insertion loss of less than 6 dB, and provides a DC port isolation of more than 35 dB. The BTL-0035SMG is available in a surface-mount package that measures 0.15 x 0.22 inches and is ideal for amplifier bias, diode bias, and DC level shifting applications.
The lower frequency of this bias tee can be extended down to 5 kHz by using an external coil and optional bypass capacitors can be added near its DC input port to filter noise on the DC line.
