New family of low-noise amplifiers for GSM, CDMA2000, WCDMA and WiMAX
Avago Technologies has announced a new family of low noise amplifiers (LNA) that are optimized for next-generation cellular infrastructure markets. With a built-in active bias circuit and current adjustable features, Avago’s miniature MGA-631P8 and -632P8 are specifically designed for easy integration into the receiver chain for GSM, CDMA2000, WCDMA and WiMAX base stations and repeaters.
By integrating the external bias circuit into the chip, Avago’s new MGA-631P8 and 632P8 provide better temperature response, simplify product design and reduce PCB space. Additionally, a current adjustable gain feature enables customers to tune the LNA to the desired gain fitting, thus lowering bill of materials. Avago has integrated these new features into a compact form factor while continuing to provide industry-low noise figures with superior linearity.
Avago’s miniature MGA-631P8 and -632P8 LNAs are available in 2.0 mm x 2.0 mm x 0.75 mm leadless packages. In 5000-piece quantities, pricing begins at $2.13. The product is available through Avago’s direct sales channel and worldwide distribution partners.
