Certain characteristics of circuit materials can indicate whether a material will contribute to higher or lower levels of PIM for a printed-circuit RF/microwave antenna.
Researchers explored the capabilities of metamaterials as microwave circuit substrates.
To meet the needs of today’s military, the RF/microwave industry is coming up with flexible, cost-effective solutions that push the technology envelope.
Ascending from its nascent potential, gallium nitride is now a mainstream technology as evidenced by its adoption into more commercial applications.
These evolutionary circuit laminates represent cost-effective solutions for low-loss antennas and active antenna arrays, both in current 4G and emerging 5G wireless systems.
Dielectric constant and dissipation factor are among the essential material parameters used by circuit designers and they must be measured precisely for accurate models.
GaN has emerged as the leading semiconductor material for high-power microwave switches and amplifiers, although GaAs is still the material of choice for low noise.
