Description

The SKY65330 is a transmit/receive Front-End Module (FEM)

designed for Skyworks Femto Base Station RF Subsystem. This

subsystem is intended for multi-band Global System for Mobile

Communications (GSM), General Packet Radio Service (GPRS),

and Enhanced Data Rate for GSM Evolution (EDGE) femto base

stations and cellular repeaters. The subsystem supports the

GSM850, EGSM900, DCS1800, and PCS1900 bands.

The SKY65330 provides a complete transmit path from

transceiver output to antenna. The module has impedance-

matching circuitry for 50 Ω inputs and outputs, and integrates

transmit harmonic filtering, an integrated coupler, and high-

GSM850, EGSM900, DCS1800, and PCS1900 bands

JEDEC J-STD-020) package

Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances) compliant packaging.

linearity and low insertion-loss pHEMT RF switches. A custom

BiCMOS integrated circuit provides the internal PAC function,

interface circuitry, and decoder circuitry to control the RF

switches.

Two Heterojunction Bipolar Transistor (HBT) PA blocks are

fabricated onto an Indium Gallium Phosphide (InGaP) die; one

block supports the GSM850 and EGSM900 bands, the other

supports the DCS1800 and PCS1900 bands. Both PA blocks share

common power supply pins to distribute current. Outputs from the

PA blocks and four receive pins connect to the antenna using

pHEMT RF switches. The InGaP die, the Silicon (Si) die, the

pHEMT die, and the passive components are mounted on a multi-

layer laminate substrate, and the entire assembly encapsulated

with plastic overmold.

Three external control pins facilitate band selection, and control of

the transmit and receive RF signal flows. Pin signals BS0 and BS1

select GSM850, EGSM900, DCS1800, or PCS1900 modes. The

TR_EN pin signal selects the transmit or receive mode of the

respective RF switch. Proper timing of the pin signal logic and

power control (the VPC pin) allows high isolation between the

antenna and the radio transceiver output.

The PAC_EN signal enables the PAC circuitry to minimize battery

drain. The low leakage current (6.5 µA, typical) of the dual PA

module maximizes handset standby time.

Feedback signals from the SKY65330 to the transceiver form an

integral portion of the Skyworks Polar Loop™ architecture. This

architecture autonomously splits amplitude and phase using the

traditional analog In-Phase and Quadrature (I/Q) signals. The

filter-saving advantage of the translation-loop approach is

embedded in the architecture. Also included is an AM loop that

provides both signal AM and power level control.
