Description

The SKY77414 Front-End Module (FEM) is a fully matched, 22-pin surface mount module developed

for WCDMA applications. Small and efficient, this WCDMA FEM integrates the interstage filter, the

input matching, the power amplifier, the output matching, the power detection, and the duplexer into

a single 5 mm x 8 mm x 1.5 mm package.

The SKY77414 meets the stringent spectral requirements of HSDPA (High Speed Downlink Packet

Access) up to 23.9 dBm output power. The FEM incorporates an InGaP HBT PA and contains circuitry

to optimize power detector performance. Different control pins are available to enhance the

performance of the FEM at different power levels.

Integration of the RF front-end greatly simplifies the design of the handset radio as all critical

matching between the interstage filter, PA, power detection, and duplexer is optimized within the

module. By optimizing the efficiency of the InGaP HBT PA MMIC and reducing the RF loss between the

integrated components, this FEM achieves current as low as 470 mA at maximum output power

(23.9 dBm) that significantly improves the talk time of the WCDMA handset. This small package uses

Skyworks’ low cost, multi-laminate substrate technology and is approximately half the size of

individually packaged component solutions. The SKY77414 front-end module can save handset

designers significant board space and design-cycle time.
