RF Pcb

RF printed circuit boards Radio Frequency PCB Quick detail: Base material: Rogers/Teflonlaminate Copper weight: 0.5OZ-3OZ Board thickness:0.1-3MM Min line width and space:3mil Min hole:0.1mm Surface finish: Immersion gold Delivery time:3-7days Min order:1pcs Rogers laminate widely used in Microwave/RF filedRF pcb(radio frequency pcb): RF electromagnetic wave is defined by the application division, specifically refers to electromagnetic waves with a certain wavelength can be used for radio communication. Frequency range defined confusing, information has 30MHz to 3GHz, there 300MHz to 40GHz, and microwave overlap; Another kind is by definition spectrum allocation refers to the wavelength of electromagnetic waves within 1m range from 1 trillion m to its corresponding frequency from 30Hz to 300MHz; radio frequency (RF) and microwave frequency boundaries rather vague, and with advances in device technology and design methods which had been changed.RF PCB and Features PCB design considering the particularity of the main circuit model considering the PCB transmission line. Since the transmission line using the line lumped parameter circuit model and distributed parameter circuit model can be considered l / λ≥0.05 (where,l is the geometrical length; λ is the operating wavelength). Defined in this specification refers to the transmission line structure RF link distributed parameter model using an analog signal circuits. PCB line length rarely more than 50cm, it is considered the lowest frequency of 30MHz analog signal can be; As more than 3G is generally considered to be pure microwave, consider this far down; consider the production process element spacing up to 0.5mm, can also be considered given the highest frequency at 30GHz, the feeling of little significance. In summary, we can consider RF PCB PCB can be defined as the frequency range of 30MHz to 6GHz analog signal having, but the specific use or distribution of lumped parameter model can be determined according to the formula.High frequency pcb RF material: Rogers4003C: thickness(0.254 0.508、0.813、1.524) DK 3.38 Rogers4350B: thickness(0.254 0.508、0.762、1.524) DK 3.5 Rogers5880: thickness(0.254 0.508、0.762) DK 2.2 Rogers3003: thickness(0.127,0.508、0.762、1.524) DK 3 Rogers3010: thickness(0.635) DK 10.2 Rogers3206: thickness(0.635) DK 10.2 Rogers3035: thickness(0.508) DK 3.5 Rogers6010: thickness(0.635,1.27) DK 10.2
