Microwave Circuit Design Advantages Using TP-1/2
Stable Dielectric Constant and Operating Temperature
The dielectric constant of TP-1/2 is stable and can be customized within the range of 3.0 に 22.0, depending on the specific requirements of the circuit design. The operating temperature ranges from -100 degrees Celsius to +150 摂氏.
Reliable Peel Strength and Lower Manufacturing Costs
TP-1/2 offers a more reliable peel strength between copper and the substrate compared to vacuum film coating on ceramic substrates. This makes it easier for customers to process circuits with higher pass rates and significantly lower manufacturing costs than ceramic substrates.
Low Dissipation Factor and Mechanical Manufacturability
TP-1/2 has a dissipation factor (tgδ) of ≤1*10^-3, with minimal variation as frequency increases. It is also easily machinable through processes such as drilling, パンチング, grinding, 切断, and etching, which are not possible with ceramic substrates.
