FLORIDA RF Labs, a Smiths Interconnect company, represented by ASD Technology , has introduced a line of coaxial dc block devices that are ideal for use in applications from dc to 10GHz.

The dc block circuit features a capacitor in series with the conductor, which prevents dc current flow while permitting RF power to flow through the dc block.

Reliability and continuous performance of the range is ensured by a rugged construction based around a stainless steel body and alumina substrate.

Standard connectors for the dc block are SMA and Type N, with other connector types available on request.

Key features include a maximum voltage of up to 75V, insertion loss of 1dB maximum, and an operating temperature range of -55 to 125°C.

The coaxial dc block meets all the applicable portions of the MIL-A-3933 and MIL-PRF-39012 specifications.
