Home > DC Blocks/Bias Tees |
DC Blocks and Bias Tees are primarily used in applications to inject/remove DC currents or voltages in RF circuits without affecting the RF signal through the main transmission path.
DC Blocks
RoHS compliant, INNER, OUTER & INNER/OUTER DC Blocks cover wireless band applications from 0.400 – 3.000 GHz. Available in N, BNC, TNC, SMA & 7/16 DIN configurations with RF power ratings to 500 watts (2.5 kW peak) and breakdown voltages to 2.5 kV making them ideal for eliminating unwanted DC voltages or surges to tower top amplifiers or sensitive lab equipment. Most models available STOCK - 2 weeks ARO. Made in USA. |
