DC blocks
Staff -- Test & Measurement World, 5/1/2005
The HR-20 series of DC blocks offers 500-W power capability with loss of less than 0.08 dB over a broad frequency range, from UHF wireless to the W-LAN band of 380 MHz to 2700 MHz. You can use the blocks to prevent the flow of direct current and low-frequency current surges along the inner conductor of a transmission line, while permitting the unimpeded flow of RF signals. Units have a high voltage tolerance of 3 kV and are moisture-sealed for outdoor applications. Microlab/FXR, www.microlab.fxr.com.
