PRODUCT SUMMARY

SKY77344 PA Module for Quad-Band GSM / EDGE

Applications

Description

The SKY77344 Power Amplifier Module (PAM) is designed in a compact form factor for quad-band

cellular handsets comprising GSM850/900, DCS1800, PCS1900, supporting GMSK and linear EDGE

modulation. Class 12 General Packet Radio Service (GPRS) multi-slot operation is also supported.

• Quad-band cellular

handsets:

GMSK Modulation

- Class 4 GSM850/900

- Class 1 DCS1800/

PCS1900

- Class 12 GPRS multi-slot

operation

The module consists of a GSM850/900 PA block and a DCS1800/PCS1900 PA block, impedance-

matching circuitry for 50 Ω input and output impedances, and a Multi-function Power Amplifier

Control (MFC) block. A custom BICMOS integrated circuit provides the internal MFC function and

interface circuitry.

Two separate Heterojunction Bipolar Transistor (HBT) PA blocks are fabricated onto a single InGaP die;

one supports the GSM850/900 bands, the other supports the DCS1800 and PCS1900 bands. Both PA

blocks share common power supply pads to distribute current. The InGaP die, the silicon die, and the

passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated

with plastic overmold.

EDGE modulation

- Class E2 GSM850/900

- Class E2 DCS1800/

PCS1900

RF input and output ports are internally matched to 50 Ω to reduce the number of external

components. Extremely low leakage current (2.5 μA, typical) maximizes handset standby time. Band

select (BS) circuitry selects GSM transmit frequency band (logic 0) and DCS/PCS transmit frequency

band (logic 1). MODE circuitry selects GMSK modulation (logic 0) or EDGE modulation (logic 1). VRAMP

controls the output power for GMSK modulation and provides bias optimization for EDGE modulation

depending on the state of MODE control.

Features

• High efficiency:

- GSM850 51% @

34.5 dBm

- GSM900 50% @

34.5 dBm

- DCS1800 50% @

32.5 dBm

The integrated multi-function control (MFC) provides closed loop power control in GMSK mode,

reducing sensitivity to antenna load, input drive, temperature, power supply, and process variation. In

EDGE mode, the MFC configures the PA for fixed gain, and provides the ability to optimize the PA bias

operation at different power levels.

- PCS1900 48% @

32.5 dBm

• Input/Output matching

50 Ω internal (with DC

blocking)

• Integrated Couplers and

Detector

• Detector Output Linear dB/V

• 20-pad MCM

• Small outline: 5 x 5 mm

• Low profile: < 1 mm
