Microwave PCB Boards Built On RO4350B 10 Mil With Immersion Gold
Just as its title implies, high frequency is that the frequency is comparatively high, typically refers to the frequency of >=300 MHz (i.e. wave size =1GHz is known as microwave.
Typical frequencies for wireless applications:
* Present mobile: 0.9GHz - 2GHz
* 3G techniques: 2.5GHz
* Bluetooth: 2.5GHz
* GPS: 12.6GHz
* LMDS: 24GHz and 40GHz
* Automotive: 77GHz
Market: RFID, Wireless communications, base station and antenna, amplifier, army products, client electronics.
High frequency printed circuit board or microwave PCB refers to the printed circuit board made on the high frequency (microwave) substrate copper clad plate. The frequent varieties are: Double-sided board, multilayer board and mixed construction.
Mixed structure includes excessive efficiency special substrate, PP sheet + extraordinary efficiency board and PP sheet combined urgent board; excessive frequency substrate + strange FR4 substrate; high frequency substrate + steel base etc.
Ceramic-stuffed PTFE composites, which have distinctive electrical and mechanical stability. Rogers RO3000 sequence circuit supplies have constant mechanical properties, regardless of the dielectric fixed (Dk) selected, which allows multi-layer board designs that use completely different dielectric constant materials without encountering warfare-web page or reliability problems. The Taconic RF series of products has a low dissipation issue with excessive thermal conductivity possible so it is not going to oxidize, yellow, or present upward drift in dielectric fixed and dissipation issue like its hydrocarbon-based opponents.
Multilayer PCB stackups are a wonderful possibility should you want increased functionality on your PCB. While manufacturing prices and design needs improve with each additional layer, the commerce-off for performance and EMC enhancements can easily be price the fee, especially with the world becoming increasingly compact. Regardless of the variety of layers you need, nonetheless, you also want an skilled PCB supplier. Millennium Circuits might help.
