30 Mil RO4730 Laminates High Frequency PCB 2 Layer

Rogers' RO4730G3 high frequency laminates are a dependable choice for antenna-grade printed circuit board substrates, offering a cost-effective alternative to traditional PTFE-based antenna substrates while enabling designers to fine-tune cost and performance. With a dielectric constant of 3 and a loss tangent of 0.0028 at 10 GHz, it also boasts a low thermal coefficient of dielectric constant (TCDk) of only 34 ppm/°C across a temperature range of -50°C to 150°C. Additionally, these high frequency PCBs have demonstrated low PIM performance, with a value of -165 dBc. The CTE values on both the X and Y axes are similar to that of copper, and the Z-axis CTE is impressively low at 30.3 ppm/°C. This superb CTE match significantly reduces stresses in the PCB antennas.
