DC-Blocks up to 110 GHz

DC-Blocks up to 110 GHz are high-frequency coupling components that block DC voltage components while allowing AC signals to pass through unimpeded. They protect sensitive RF circuits from unwanted DC offsets and ensure optimal signal integrity across a broad frequency spectrum.

Key Features

• Frequency range up to 110 GHz for modern mmWave and THz applications
• Low insertion loss and high return loss (VSWR-optimized)
• High power handling up to 100 W – ideal for HPA and high-voltage applications
• Coaxial design with standardized connectors (SMA, SSMA, 2.4 mm, 1.85 mm)
• Reliable long-term stability under extreme thermal conditions

Applications

• Telecommunications and 5G/6G infrastructure
• SATCOM and Defense systems
• High-frequency test and measurement and laboratory equipment
• ADAS and radar systems (automotive)
• LNA, VCO, and PLL protection circuits in transceivers

DC-Blocks are critical components for signal conditioning in highly sensitive RF systems. They prevent parasitic DC voltages from damaging amplifiers or mixers and enable safe, noise-free signal transmission in CW, pulsed, and FMCW operating modes.

bq-microwave offers an extensive portfolio of DC-Blocks with various power classes, impedances, and frequency bands. All products meet Mil-Spec requirements for critical applications.
