Description
SMA DC Block | 18 GHz | Inner & Outer Conductor Isolation
The ROSNOL DBIO-A1A25A-18G200V/9XX-9X is a precision SMA DC Block designed to prevent unwanted DC voltage transmission while maintaining stable RF signal performance from 0.01 to 18 GHz. Featuring an SMA Plug (Male) to SMA Jack (Female) configuration with 50 Ω impedance, this device offers low insertion loss of ≤ 0.8 dB and VSWR of ≤ 1.35, helping preserve signal integrity across broadband RF and microwave systems. Constructed with gold-plated beryllium copper contacts, passivated stainless steel bodies, and PTFE insulation, it delivers reliable mechanical durability with a mating life of 500 cycles or more.
A key advantage of this ROSNOL SMA DC Block is its ability to provide both inner and outer conductor DC isolation while supporting frequencies up to 18 GHz and DC voltages up to 200 V. This design helps protect sensitive RF equipment, reduces the risk of unintended DC current flow, and improves system reliability. It is commonly used in RF test setups, microwave measurement equipment, laboratory instrumentation, communication systems, and other high-frequency signal transmission applications where DC isolation and signal integrity are critical.
ROSNOL’s RF passive components are manufactured in ISO 9001-certified facilities and comply with RoHS requirements, providing customers with a dependable and cost-effective solution for demanding RF and microwave interconnect applications.
