50khz-110Ghz 1.0mm broadband DC block

Leader-MW's 1.0mm broadband DC block covers 50 kHz to 110 GHz, a full waveguide-to-connector span rarely achieved in a single component. The 1.0mm connector interface is the key enabler—it supports the upper frequency limit while keeping insertion loss low across the entire band.

Key specs to note:
- Frequency range: 50 kHz – 110 GHz, continuous coverage with no gaps
- Connector: 1.0mm female/female (standard), designed for V-band and W-band test setups
- DC blocking:Typically blocks DC while passing RF, with a specified cutoff at the low end
- Power handling:Rated for moderate power levels, suitable for bench testing and signal integrity work

Typical applications:
- Broadband test and measurement (VNA calibration, signal generators)
- 5G/6G mmWave R&D, radar, and satellite communication systems
- Protecting sensitive equipment from DC bias while maintaining RF transparency

Design advantages:
- Single-component solution eliminates the need for cascaded blocks, reducing mismatch and loss
- Precision 1.0mm interface ensures repeatable performance and low VSWR
- Compact form factor fits into dense test fixtures

Caveats:At 110 GHz, connector mating quality and torque are critical—use proper torque wrenches and inspect mating surfaces. Verify the specific DC cutoff frequency and insertion loss from the datasheet, as these vary by model. For high-power or high-reliability applications, confirm derating curves with the manufacturer.
