3. TECHNICAL BRIEF

3.1 Power Amplifier (SKY77318, U502)

The SKY77318 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form

factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation.

The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation. The

module consists of separate GSM850/900 PA and DCS1800/PCS1900 PA blocks,

impedancematching circuitry for 50 Ω input and output impedances, and a Power Amplifier Control

(PAC) block with an internal current-sense resistor. The custom BiCMOS integrated circuit provides

the internal PAC function and interface circuitry. Fabricated onto a single Gallium Arsenide (GaAs) die,

one Heterojunction Bipolar Transistor (HBT) PA block supports the GSM850/900 bands and the other

supports the DCS1800 and PCS1900 bands. Both PA blocks share common power supply pins todistribute current. The GaAs die, the Silicon (Si) die, and the passive components are mounted on a

multi-layer laminate substrate. The assembly is encapsulated with plastic over mold. RF input and

output ports of the SKY77318 are internally matched to a 50 Ω load to reduce the number of external

components for a quad-band design. Extremely low leakage current (2.5 µA, typical) of the dual PA

module maximizes handset standby time. The SKY77318 also contains band-select switching circuitry

to select GSM (logic 0) or DCS/PCS (logic 1) as determined from the Band Select (BS) signal. In

Figure 3.1 below, the BS pin selects the PA output (DCS/PCS OUT or GSM850/900 OUT) and the

Analog Power Control (VAPC) controls the level of output power. The VBATT pin connects to an

internal current-sense resistor and interfaces to an integrated power amplifier control (iPAC™)

function, which is insensitive to variations in temperature, power supply, process, and input power.

The ENABLE input allows initial turn-on of PAM circuitry to minimize battery drain.

3. TECHNICAL BRIEF


3.2 Transceiver (AD6548, U503)

The AD6548 provides a highly integrated direct conversion radio solution that combines, on a single chip, all

radio and power management functions necessary to build the most com-pact GSM radio solution possible.

The only external components required for a complete radio design are the Rx SAWs, PA, Switchplexer and

a few passives enabling an extremely small cost effective GSM Radio solution. The AD6548 uses the

industry proven direct conversion receiver architecture of the OthelloTM family. For Quad band applications

the front end features four fully integrated programmable gain differential LNAs. The RF is then down

converted by quad-rature mixers and then fed to the baseband programmable-gain amplifiers and active

filters for channel selection. The Receiver output pins can be directly connected to the baseband analog

processor. The Receive path features automatic calibration and tracking to remove DC offsets. Thetransmitter features a translation-loop architecture for directly modulating baseband signals onto the

integrated TX VCO.

The translation-loop modulator and TX VCO are extremely low noise removing the need for external SAW

filters prior to the PA. The AD6548 uses a single integrated LO VCO for both the receive and the transmit

circuits. The synthesizer lock times are optimized for GPRS applications up to and including class 12.

AD6548 incorporates a complete reference crystal calibration system. This allows the external VCTCXO to

be replaced with a low cost crystal. No other external components are required. The AD6548 uses the

traditional VCTCXO reference source. The AD6548 also contains on-chip low dropout voltage regulators

(LDOs) to deliver regulated supply voltages to the functions on chip, with a battery input voltage of between

2.9V and 5.5V. Comprehensive power down options are included to minimize power consumption in normal

use. A standard 3 wire serial interface is used to program the IC. The interface features low-voltage digital

interface buffers compatible with logic levels from 1.6V to 2.9V.

3. TECHNICAL BRIEF

3.4 26 MHz Clock (Crystal, X501)

The 26 MHz clock (X501) consists of a XO( Crystal Oscillator) which oscillates at a frequency of 26

MHz. The AD6548 requires only an external low cost crystal as the frequency reference. The circuitry

to oscillate the crystal and tune its frequency is fully integrated. The Oscillator is a balanced

implementation requiring the crystal to be connected across 2 pins. There is a programmable capacitor

array included for coarse tuning of fixed offsets (e.g. crystal manufacturing tolerance), and an

integrated varactor for dynamic control. The oscillator is designed for use with a 26MHz crystal.

Dedicated control software ensures excellent frequency stability under all circumstances.

3. TECHNICAL BRIEF


3.8 Keypad Switches and Scanning

The key switches are metal domes, which make contact between two concentric pads on the keypad

layer of the PCB when pressed. There are 27 switches (Normal Key 23EA, Volume up down and

camera side key, PWR down side key), connected in a matrix of 6 rows by 5 columns, as shown in

Figure 3-11, except for the power switch (END), which is connected independently. Functions, the row

and column lines of the keypad are connected to ports of AD6721. The columns are outputs, while the

rows are inputs and have pull-up resistors built in. When a key is pressed, the corresponding row and

column are connected together, causing the row input to go low and generate an interrupt. The

columns/rows are then scanned by AD6721 to identify the pressed key.

3.9 Microphone

The microphone is placed to the Front cover and contacted to main PCB. The audio signal is passed

to MIC_N and MIC_N pins of AD6721. The voltage supply VMIC is output from AD6721, and is a

biased voltage for the MIC_P. The MIC_P and MIC_N signals are then A/D converted by the voice

band ADC part of AD6721.

The digitized speech (PCM 8KHz ,16KHz) is then passed to the DSP section of AD6721 for

processing (coding, interleaving etc).

3. TECHNICAL BRIEF


3.15 BLUETOOTH & FM Radio (BCM2048, U600)

The Broadcom BCM2048 is a monolithic single-chip, Bluetooth 2.0+EDR-compliant, baseband

processor/2.4-GHz transceiver with an integrated FM and RDS/RBDS receiver. It features the highest

level of integration and eliminates all critical external components, thereby minimizing the footprint,

power consumption, and system cost of a Bluetooth plus FM radio solution.

The BCM2048 also supports key features of upcoming Bluetooth standards and offers a firmware

migration path to new features. The BCM2048 is the optimal solution for any Bluetooth voice or and/or

data application that also requires a FM radio receiver. The Bluetooth subsystem presents a Host

Controller Interface (HCI) using a high speed UART and PCM for audio. The FM subsystem supports

I2C compatible control interface and stereo analog output, as well as I2S and PCM interfaces. TheBCM2048 incorporates all Bluetooth 2.0 features including eSCO, AFH, and Fast Connect as well as

support for InConcert collaborative coexistence with WLAN devices.

The BCM2048 Bluetooth radio transceiver provides enhanced radio performance to meet the most

stringent handset temperature applications or the tightest integration into mobile handsets and

portable devices. It is fully compatible with any of the standard TCXO frequencies and provides ful

radio compatibility to operate simultaneously with GPS, WLAN, and cellular radios.
