RT/duroid 6006 is selected when circuit area is expensive. Its high dielectric constant can shorten filters, resonators, patch antennas and amplifier matching networks, but the smaller geometry brings tighter tolerance and stronger temperature sensitivity. The useful...

RT/duroid 5870 is chosen when the RF path needs low loss, low dielectric constant and broad-frequency stability, but the manufacturing route is less forgiving than a standard thermoset laminate. The same PTFE-rich structure that supports wideband antennas and long...

TMM3 is selected when an RF circuit must behave as part of a mechanical module. The board may include machined cavities, mounting holes, plated edges, wire-bond pads, clamps or a metal housing. In that environment, low loss is only one requirement; rigidity,...

A 77 GHz radar board is purchased as a working sensor platform, not as a sheet of RO3003. The customer ultimately cares about antenna alignment, feed-network phase, launch return loss, assembly consistency and radar performance over temperature. That is why a radar...

RO4835T is useful when the RF layer must move inside the multilayer stack without consuming the thickness of a conventional microwave core. The buying decision is therefore tied to board architecture: dense radio modules, phased-array feed networks, compact...

RO4003C is often the point where an RF project stops behaving like an ordinary FR-4 board. The change is not driven by the material name alone. It normally happens because insertion loss, phase consistency, filter response, antenna feed stability or production...
