In the field of Polar Edge Pam, TriQuint is very advantageous, and market share is ranking first in the world. Triquint China Manager Xiong Ting said, "So far, our Polar PAM shipments have exceeded 2 billion pieces, and the market share has exceeded 50%." These products have received Qualcomm and MTK recognition. TQM7M5022 is the company's fifth-generation Polar Edge PAM product that is compatible with the 5012 / H pin. Compared with the previous generation of products, their costs and performance have been maximized. It uses Cuflip hot cooling technology, world-class Switching ORFS and excellent cross-band PAE features, it is still the cheapest Polar solution. "Our solutions include two chips, high-frequency and low frequency separation, but the area is small than a piece of chip of competition products." 55mm flip-clip) package makes the chip size reduced by 25%, while competition The product is 55mm wire, and the CMOS area is 45% (Figure 2).
"The product has increased by 52%, but I think this will be the last generation of Polar Pam products. After 3 years, Polar PA may gradually fade out the market." Xiong Tang pointed out, "The mainstream of the next generation of Edge will be Linear EDGE. The appearance of linear PA is mainly integrated for the next step and WCDMA PA, and if all of the WCDMA is linear, all WCDMA is linear, and this multimode Pa will necessarily require linear EDGE PA. "
In the two major camps of Edge Pam, the market is beginning to gradually tilting linear PAs, British PA, St-Ericsson, Datang, Haisi and other companies use linear Pa, Although Qualcomm is currently supported by Polar Pa However, the transition is also used in the future.
In order to cooperate with Qualcomm's next-generation linear Edge, TriQuint launched the first linear power amplifier module TQM7M5013. This is a 55mm four-band linear EDGE power amplifier module, which uses the innovative architecture that can significantly improve energy efficiency and extend user talk time. Compared to the previous generation of TQM7M5012, the product can extend 15% GSM average talk time. This high-efficiency PAM provides components for the next generation of fuse / multimode amplifiers, and TQM7M5013 supports the latest 3G high-pass chipset, which can be used to configure more than 10 platforms launched in 2010.
Xiong Ting further explained that for linear PAs, there is a need to hiera between linearity and efficiency. If you want to maintain a very high linearity, it will be low, and the vice versa will fall rapidly. The introduction of predistortion technology ensures balance between the two. When the linearity is slightly decreased, the efficiency will reach the optimality when the system indicator requirements are met. Therefore, TQM7M5013 has seven power states that can be biased in different locations, ensuring optimal linearity and efficiency hits in a certain power interval.
TriQuint has continuously promoted the growth of China RF market in recent years. Since 2005, TriQuint has increased by 40% in the China market, providing a complete radio frequency solution for Chinese customers, covering 2G / 2.5G (GSM / GPRS / EDGE), 3G (CDMA / EV-DO, WCDMA / WGPRS / WEDGE, 4G (LTE), wireless LAN and Bluetooth and mobile devices, etc. In addition, TriQu is fully supported by covering the full-time sales team of China, experienced engineers, comprehensive radio frequency laboratory and custom design and application support for customers.
