DC BLOCK 158 FREQUENCY RANGE: 1 - 1000 MHz DUAL BLOCK DC BLOCK Because of their inherent high breakdown potential, the DC Blocks are ideal for applications where a high voltage, DC or AC up to 20 KHz, must be rejected from the RF signal path. Leakage from modulating signals can occur via AC power lines, through ground loops, or along poorly grounded coaxial cables. These leakages can impair the accuracy of RF measurements, and or signal purity.
