TPH-1/2 is made of a new type of inorganic and organic materials,with special process and compounding.
The advantage of design for microwave circuit using TPH-1/2 here:
(1)The substrate is black. The dielectric constant is 2.65,with consistent performance over broad temperature and frequency ranges. The operating temperature is -100 degree Celsius～+150 degree Celsius;
(2)The peel strength between the copper and the substrate is more reliable than the vacuum film coating of ceramic substrate. This substrate is created to offer customers easy for circuit processing,higher pass-rate of production,and the manufacturing cost is much lower than the ceramic substrate.
(3)Dissipation factor tgδ≤1*10-3,and the loss has a slight variation with the rise of the frequency.
(4)It is easy for mechanical manufacturing,including drill, punch, grind, cut, etching,etc.. For these,the ceramic substrate cannot be compared.
(5) Due to the specific gravity less,the remarkable characteristics of the module are weight lighter manufacturing by this substrate,which but other materials cant compare.
(6)Copper thickness is:0.035μm

printed circuit board(PCB) with radio frequency(RF PCB) are an increasingly used technique within the PCB industry.
--RF PCB with a high frequency with works above 100 MHz.
--Microwave Circuit with works above 2 GHz radio frequency.
RF-pcb’s are used in different applications such as remote controls(wireless controls)security,smartphones,sensors etc.
New technologies make more and more use of these RF applications.
This asks for a manufacturing according to high quality standards and choosing the right RF materials depending on the application.
It is important that one knows the properties of the various materials. Choosing the right material is perhaps the most critical decision in the production process of the RF PCB.
