Global LTE has entered the stage of rapid development , China is expected to release in late 2013 4G commercial licenses , operators have begun a large-scale investment in 4G network infrastructure . "4G networks can bring higher bandwidth and spectrum utilization, the benefits of our mobile phone users is speed faster, stronger signal . 4G technology trends for materials brought some new challenges ." Said Yang Xi .
Yang Xi further explained that the challenges facing the RF plate mainly for the following three aspects:
First, a wider bandwidth . Wide bandwidth requirements to consider when designing circuits for more details . For example , a lower insertion loss, more PA module , and a smaller area of the board layout .
Second, the power is even greater. The larger the output power generated by the more heat loss , so we need better cooling and a larger area for heat dissipation. It is precisely with the first trend is contradictory.
Third , 4G developments tend to be an integrated . For example , there are many needs amplifier with integrated antenna design , such as small base station design, active antenna design. Enhance the speed of return requirements to improve , so you need to use higher frequencies in the pursuit of greater bandwidth. So these requirements for RF plates bring a very big challenge.
Based on consideration of the above factors, Rogers for the 4G market , respectively, introduced the corresponding products.
( 1 ). 4G antenna market requirements antenna material with excellent passive intermodulation (PIM) performance, and rigidity, light weight and low cost manner . For 4G antenna market, Rogers launched RO4700JXR ™ series antenna products. The series of materials with excellent mechanical and electrical properties, the texture is very light and can be laminated plywood ( laminated plywood antenna for PFTE class in terms of higher difficulty of processing the material , the cost is higher ) , while reducing PIM values. RO4700JXR base can be used , RFID and other antenna designs, such as a base station for antenna design , the integrated power amplifier designed for a micro base station antenna , the antenna at the AAS integrated amplifier design, the need to use the power amplifier and the other antenna, and more Laminates complex antenna and antenna system. In other words, RO4700JXR make up the gap multilayer antenna.
( 2 ). 4G PA market will move higher power, more compact circuit design and trends in the development of better stability. For 4G PA market , Rogers launched RO4360G2 ™ laminates. The material has a dielectric constant of 6.15 (DK) value, high DK can reduce the size of the circuit board. The power amplifier and antenna miniaturization miniaturized applications, RO4360G2 very valuable.
( 3 ) high-power PA required materials have lower insertion loss and higher thermal conductivity ( TC higher value ) to help reduce the temperature. For high power PA market , Rogers launched RO3006HTC ™ laminates. The product has a high thermal conductivity, up 1.75W/mK, can help reduce the temperature of PA board , to enhance long-term reliability of the PA circuit. In addition , RO3006HTC can better reduce the insertion loss .
( 4 ) With the passage of time and changes in temperature , oxidation of the plate be affected. In the long run , will lead oxide dielectric constant and loss factor of the plate line small changes occur . For applications requiring higher at high temperature stability , Rogers RO4835 ™ developed a line of sheet metal. It is an original RO4350B ™ improves the oxidation resistance of the material . Its antioxidant properties increased 10-fold. Moreover , the electrical and mechanical properties RO4350B almost the same RO4835 .
Yang Xi stressed that " for this broadband, high-power, and have higher expectations of 4G products on the complexity of the design can be described Rogers takes into account all aspects of it ."
New challenges in the field of aerospace and reliable high frequency high material
In recent years , with the rapid development of China s manned spaceflight, space technology, satellite communications and other fields of academic research , the demand for high-frequency materials skyrocketed . Moreover, with the use of the frequency and high-frequency signal transmission equipment to the high-frequency signal processing equipment GHz, THz transferred from MHz, high-frequency performance of the material is also put forward higher requirements.
"The electronics industry has developed rapidly , requiring more material loss, more stable , compatible with high-density design and environmentally friendly performance . These requirements mean that the market needs more low loss tangent (Df) of the material to produce a lower insertion loss and higher performance products. long-term stable performance, wide bandwidth and large temperature range, it becomes even more important than ever . further, higher Dk high-density design requirements to achieve a compact design , and higher thermal conductivity to achieve long-term stability. Meanwhile , high-density multi-layer manufacturing process design requirements are compatible . " Yang Xi said .
Address these challenges , Rogers combines original technologies for more targeted research and development of new products to meet market demand .
( 1 ) Low-loss products: With the enhancement of the data rate , high-frequency data sheet requires less insertion loss . RO3000 ® laminate ceramic filler is added PTFE composite materials have the lowest commercial loss . For commercial microwave and RF applications. The series provides extraordinary electrical and mechanical stability.
( 2 ) high stability :. RO4835 laminate suitable for the requirements in high temperature stability and higher than the standard RF thermoset material more resistant to oxidation applications. Its antioxidant activity than the original RO4350B increased 10 -fold.
( 3 ) High TC Materials :. RT / duroid ™ 6035HTC laminates are ceramic-filled PTFE components of high frequency circuit materials with high thermal conductivity, high power RF microwave applications designed for .
( 4 ) Easy processing: processing RO4000 ® laminates series of material similar to FR-4, for automated placement .
In addition , RT / duroid 5000 and RT / duroid 6000 laminates also have excellent electronic properties, widely used in highreliability , aerospace applications. All materials Rogers RoHs compliant .
Focus on customer needs continued investment in the Chinese market
Rogers Corporation is a leader in high-frequency circuit board material , with 180 years of materials science and process knowledge . In the course of its development , Rogers has been the successful development and adjustment of product , technology and production facilities to meet the needs of existing and emerging markets . From the inception of the company in 1832 as a manufacturer of cardboard to now , Rogers has become the world s leading supplier of special materials , covering a number of high-tech equipment and systems. In the past few decades , Rogers is more focused on the RF industry , and continue to build their expertise , technologies and products .
Talking about how to get ahead and remain competitive advantage in the fierce market competition , Sheryl Long said, " the customer is the first one. We actively listen to our customers ideas and improve our products and services to better meet customer needs , we not only have a sales staff and customer dialogue , as well as a large number of local service technicians , engineers, and marketing manager of application development support to customers we are committed to a deep understanding of customers, target market and our technology has made great by the way how influence .
