TAIYO YUDEN has announced the availability of its AQ105 series of high-frequency inductors for matching-circuit applications in cell phones, notebook PCs and other wireless-enabled computer and communications devices. AQ105 series inductors employ a proprietary simulation technique that optimally characterizes the device’s structural attributes to produce a typical Q value improvement of 100% or higher, compared to the company’s earlier, industry-leading HK series inductors. At a measuring frequency of 0.8GHz, for example, the AQ105-2N2 device achieves a typical Q value of 67 versus 31 for the HK1005-2N2 series device with similar physical and electrical characteristics. At 1.8GHz, the same AQ series part provides a Q value of 101.

This is important because cell phones, notebook PCs, PDAs and other computer and communications devices are increasingly integrating Bluetooth®, wireless LANs, radio, TV and even GPS reception, into the same unit. Sending and receiving on multiple frequencies in a single device requires a large number of matching circuits to ensure proper operation of high-frequency circuits and modules. For this reason, demand has greatly increased for the types of high-frequency inductors critical to this application.

In response to this challenge, TAIYO YUDEN became an early market leader in matching-circuit applications with its HK series of compact, high-frequency inductors combining high performance with easy mountability. However to take inductor performance to the next level, TAIYO YUDEN employed its industry-leading material science expertise to develop a special “structural characteristic simulation” that resulted in the AQ105 series of high-frequency inductors that improved typical Q factor by 100% or more compared to previous HK series devices with similar physical and electrical characteristics.
