Description

A DC block on the inner conductor with N male to N female connectors, operating from 10 MHz to 18 GHz, is a precision RF component used to prevent the flow of direct current (DC) through the center conductor of a coaxial transmission line—while allowing RF signals to pass with minimal loss. This is especially useful in test setups, bias-sensitive circuits, and systems where DC isolation is required between components. 🔧 Key Specifications (based on the Pasternack PE8213 and HASCO HDC18NI models): - Block Type: Inner (capacitor in series with center conductor) - Frequency Range: 10 MHz to 18 GHz - Impedance: 50 ohms - VSWR: ≤ 1.35:1 - Insertion Loss: ≤ 0.6 dB - Power Rating: Typically 5 watts average - Connectors: N male to N female - Construction: - Body: Passivated stainless steel or anodized aluminum - Contact: Gold-plated beryllium copper - Dielectric: High-temperature plastic or PTFE - Operating Temperature: -65°C to +125°C 🛠️ Applications: - Isolating DC bias in RF test and measurement setups - Preventing ground loops in sensitive systems - Protecting downstream components from DC voltages
