Description

A DC block on the outer conductor with SMA male to SMA female connectors, operating from 10 MHz to 18 GHz, is a specialized RF component designed to prevent direct current (DC) from flowing through the outer shield of a coaxial transmission line—while allowing RF signals to pass unimpeded. This is especially useful in systems where ground loops or unwanted DC bias on the shield could interfere with sensitive measurements or equipment. 🔧 Key Specifications (based on models like HASCO HDC18IO): - Block Type: Outer (capacitor in series with the outer conductor) - Frequency Range: 10 MHz to 18 GHz - Impedance: 50 ohms - VSWR: ≤ 1.35:1 across the full band - Insertion Loss: ≤ 0.75 dB - Power Rating: 5 watts average - Connectors: SMA male to SMA female - Construction: Passivated stainless steel body, gold-plated beryllium copper contacts, high-temp plastic dielectric - Operating Temperature: -65°C to +125°C - RoHS Compliant: Yes 🛠️ Applications: - Isolating DC bias on the outer conductor in test setups - Preventing ground loops in sensitive RF systems - Protecting equipment from unintended DC currents
