DiClad is a fiberglass-reinforced PTFE family for high-frequency circuit substrates. Use it as a construction choice for antenna and microwave work, with particular attention to reinforcement, dielectric options and how the finished panel is supported.
Compare a usable board construction
Investigate DiClad 527, DiClad 870 and DiClad 880 using the same circuit requirement. A lower dielectric constant changes physical dimensions; it does not make an existing artwork interchangeable. Confirm the available thickness, copper and dielectric specification before calculating an antenna feed.
Ask what the panel must survive
A large antenna panel experiences handling, connector attachment and mounting loads that a small coupon does not. Identify unsupported spans and avoid confusing a laminate’s published mechanical characteristics with the stiffness of a completed assembly. Prototype the mounting arrangement along with the RF layout when mechanical deformation could move the radiators or alter connection stress.
Investigate PIM variants separately
If low PIM is central, compare the exact DiClad 880-IM construction and its evidence with the base material. A low-loss dielectric alone cannot qualify the passive intermodulation of assembled connectors and joints. Use the PIM checklist and agree a realistic measurement floor, tone plan and mechanical test condition before setting acceptance.
