Zhejiang Xingyao Semiconductor Co. Ltd., formally launched its new generation of small-sized Band 2, Band 3, and Band 7 duplexer chips yesterday. All three models possess a size of 1411 (1.4mm x 1.1mm)—currently the smallest discrete duplexer chip size available globally, and a first-of-its-kind worldwide release.
These three launched duplexers are based on Xingyao Semiconductor's latest generation of TF-SAW technology and integrate several patented technologies. As a result, the total performance of the products reaches world-class standards.
The specific performance of the chips is as follows:
The Band 2 duplexer has a typical Tx band insertion loss of less than 1.7dB and a Rx band insertion loss of less than 1.8dB. With a frequency domain isolation greater than 56dB for both Tx and Rx, its overall performance surpasses leading international products of sizes 1814 and 1612.
The Band 3 duplexer features a typical Tx band insertion loss of less than 1.8dB and a Rx band insertion loss of less than 2.2dB. Its frequency domain isolation is above 55dB for both Tx and Rx bands, reaching first-tier international manufacturer’s product performance levels.
The Band 7 duplexer exhibits a typical Tx band insertion loss of less than 1.8dB with a Rx band insertion loss of less than 1.7dB. It surpasses with a Tx frequency domain isolation above 57dB and a Rx frequency domain isolation exceeding 62dB. The chip's overall performance has already attained world-class standards.
Zhejiang Xingyao Semiconductor Co. Ltd., set up in November 2020, used to be Zhejiang Xintang Zhixin Science and Technology Co. Ltd. The high-tech company that specializes in the research, production, and sales of RF filter chips and RF front-end modules is leading in developing duplexers, and filter products. To date, it has delivered several hundreds of millions of units.
