As the only company so far entrusted with national projecton TD-SCDMA and “863” project by MoST (Ministry of Science and Technology), Comlent has developed TD-SCDMA chipset CL4020 and CL4050, which are RF transceiver and ABB (Analog Base Band) respectively, and owns all IP of these products. The chipset is the only solution so far who can interface with all the domestic TD-SCDMA base band solution suppliers, i.e. Spreadtrum, COMMIT, T3G, Datang and CYIT.

Comlent has been applying more than 10 patents on this design to claim the core technology developed in 3G, which is also a solid base for Comlent’s long-term development.

Because of its advanced technology and excellent performance in CMOS technology, the technical paper to introduce this design was disclosed in Feb. 2007 on ISSCC, the worldwide top conference on IC design, which indicates China’s CMOS TD-SCDMA chipset has reached world class performance. And it was also the 1st time that Chinese company shows the design for a whole IC on ISSCC during its 54-year history. Below are the highlights of this chipset.

First, it is based on advanced CMOS technology, which implies significant room to cost down in production stage. The two major solutions from international players are still using BiCMOS technology which is more expensive. Comlent’s strategy is more suitable for China market.

Second, it uses zero-IF architecture, which has potential to optimize the performance and function. In general, zero-IF architecture would lead to more difficulty in design. But Comlent chipset uses this architecture with creativity so as to simplify the circuit design meanwhile with enough performance by maximizing digital capability and optimize the key analog blocks.

Since its commercialization in 2004, Comlent’s PHS chipset, RF transceiver CL3110 and power amplifier CL3503 has been shipped more than 1 million, and designed into more than 25 handset models and modules in over 10 customers, such as Amoi, ZTE, Corise, STC, ETTIT, WIT, Zhongxia, WITS, Yulong, Tianwei, Youtong, Joyee, and so on.

CL3213 is the 1st single-die, PA integrated RF transceiver in the world for PHS handset. It is estimated to commence mass production since Q2, 2007.

CL6010 is an FM radio single chip supporting worldwide FM bands with low power consumption for handset and portable multimedia platforms. It is estimated to commence mass production since Q2, 2007.
