The performance of signal booster PCBs is significantly influenced by the materials used in their construction. Key to this is the substrate's permittivity or dielectric constant (Dk), which affects the size of the amplifier circuits; materials with higher Dk values lead to smaller circuits, beneficial for portable and miniaturized designs. However, for high-power applications, larger circuitry may be necessary for adequate power dissipation.

Consistency of the dielectric constant across the PCB substrate is crucial for maintaining tightly controlled impedances, essential for the impedance matching of power transistors in amplifiers. Moreover, the stability of the dielectric constant with temperature changes is vital, as variations can impact amplifier performance. Materials with a low thermal coefficient of dielectric constant are preferred for their minimal change in Dk with temperature fluctuations.

Another critical factor is the dissipation factor or loss tangent, indicating the signal energy lost through the dielectric material. Lower values are desirable to minimize loss in output power and signal gain. Additionally, moisture absorption by the substrate can significantly alter the dielectric constant, impacting impedance and amplifier gain, hence materials with low moisture absorption rates are advantageous.

Lastly, the material's ability to manage heat through thermal conductivity and a low coefficient of thermal expansion (CTE) is essential, especially for high-power amplifiers where heat dissipation is critical for reliability. Materials with higher thermal conductivity and lower CTE values are better suited to withstand the thermal stresses associated with power amplifiers.
