Inner DC Blocks

The core function of DC Block is to prevent direct current (DC) signals from passing through while allowing alternating current (AC) signals, especially radio frequency (RF) signals, to pass through smoothly. This characteristic is of great importance in many circuits as it can prevent DC signals from having unwanted effects on subsequent circuits. For example, it protects sensitive RF components from the damage caused by direct current and avoids the interference of DC bias with the normal transmission of RF signals.

For some application scenarios that require connection to coaxial cables, RF DC Blocks with coaxial packaging will be used. This packaging form has excellent RF performance and anti-interference capabilities, ensuring the efficient transmission of RF signals between the coaxial cable and the internal circuit. The RF DC Block with coaxial packaging typically has a central conductor and an outer conductor pin for connecting to the outer shielding layer of the coaxial cable. The internal circuit is connected to the pins through a special RF connection structure to meet the performance requirements of low loss and high isolation. Generally, the coaxial interfaces of DC BLOCKs include various types of RF interfaces such as SMA, 2.92mm, and 1.85mm. The outer conductor is passivated with stainless steel, and the conductor material is brass plated with gold.

In wireless communication: In wireless transceivers, it is used to separate the DC and AC components of radio frequency (RF) signals. It avoids the DC bias from affecting the processing of RF signals by subsequent circuits, ensuring the normal transmission and amplification of RF signals.
