AVX Corp. has developed an integrated thin-film, high-directivity coupler that provides a directivity of 20-27dB and an ultra-tight 0.5dB coupling factor tolerance. AVX said it's the first company to offer this level of performance for directivity and coupling factor tolerance.

Based on the proprietary RFAP thin-film technology, the CP0402P series improves PA gain control in high-frequency applications such as cellular and WiMAX wireless system transmitters. The tight tolerance coupler is offered in a variety of frequency bands and can be used for power control of transmitters in cellular, GPS and wireless communications, which are key features for designers of W-CDMA, WiMAX, and WiBro systems, said AVX.

The CPO402P series coupler is available in an LGA termination, providing low profile, low parasitics and self-alignment during reflow.

Typical pricing for the AVX CP0402P is 19 cents with a 10-week lead time.
