描述 Description

The SKY77413 Front-End Module (FEM) is a fully matched, 22-pin surface mount module developedfor WCDMA applications. Small and efficient, this WCDMA FEM integrates the interstage filter, theinput matching, the power amplifier, the output matching, the power detection, and the duplexer intoa single 5 mm x 8 mm x 1.5 mm package.

The SKY77413 meets the stringent spectral requirements of HSDPA (High Speed Downlink PacketAccess) up to 23.9 dBm output power. The FEM incorporates an InGaP HBT PA and contains circuitryto optimize power detector performance. Different control pins are available to enhance theperformance of the FEM at different power levels.

Integration of the RF front-end greatly simplifies the design of the handset radio as all criticalmatching between the interstage filter, PA, power detection, and duplexer is optimized within themodule. By optimizing the efficiency of the InGaP HBT PA MMIC and reducing the RF loss between theintegrated components, this FEM achieves current as low as 450 mA at maximum output power(24.8 dBm) that significantly improves the talk time of the WCDMA handset. This small package usesSkyworks’ low cost, multi-laminate substrate technology and is approximately half the size ofindividually-packaged component solutions. The SKY77413 front-end module can save handsetdesigners significant board space and design-cycle time.
