Avago Technologies has announced the industry's smallest integrated RF front-end module for UMTS Band 1 handsets. The company is a leading supplier of innovative semiconductor solutions for advanced communications, industrial and commercial applications. Avago's new AFEM-7780 module integrates the company's innovative FBAR (Film Bulk Acoustic Resonator)-based duplexer with its advanced CoolPAM power amplifier technology to provide users with industry leading battery life, superior signal reception and high performance.

Based on wireless GSM (Global System for Mobile Communication) technology, UMTS (Universal Mobile Telecommunications System) is a worldwide communication standard which enables broadband packet-based transmission of High-Speed Downlink Packet Access (HSDPA) applications, such as text, digitized voice, video and multimedia. UMTS has begun to roll out worldwide; Band 1 is the first UMTS frequency band to be available.

Measuring 4 mm x 7 mm x 1.1 mm and supplied in a 20-pin surface mount package, the ultra-small AFEM-7780 handles critical RF functionality and frees up to 50% of PCB space on the handset currently needed for this functionality. By combining a transmitter filter, power amplifiers, coupler and duplexer into one module, the AFEM-7780 dramatically reduces the need for engineering resources and speeds time to market.

Avago's award winning FBAR-based technology provides an industry low insertion loss and outstanding isolation, which improves efficiency and receiver sensitivity and makes it perfectly suited for addressing the complexities of UMTS Band 1. Offering the lowest average operating current in the industry, Avago's CoolPAM power amplifiers provide up to 30 minutes more talk time and excellent linearity.
