Murata announces industry’s smallest isolator

23 DECEMBER 2008

Murata has developed the industry’s smallest isolator for use in 800MHz/2GHz mobile phone handset applications. The CEG23 series’ innovative construction helps to save mounting space in even the most demanding of designs. The new isolator is 56% smaller than Murata’s previous generation of isolators, measuring a tiny 2.0 x 2.0 x 1.0mm. As the trend for high performance and multiple features in mobile phones advances, the demand for smaller electronic components from manufacturers is growing stronger. With the expansion of the multi-band mobile phone market, demand for smaller versions of the RF circuits responsible for wireless communications is especially strong. An isolator is a passive device containing ferrite material which is used to protect other parts of the circuit such as the power amplifier from excessive signal reflection, and as a result, it contributes to better signal quality.
Murata’s CEG23 series offers an LGA (land grid array) terminal, reducing mounting space and increasing freedom in RF circuit design.
