■ Main PCB Description

All components required for the RF and Logic circuits, excluding the LCD module, are contained on a single
printed circuit board (PCB). The PCB has six layers with lay1-2 and layer 5-6 build-up Surface and back layer
tracks are gold-plated to prevent oxidization and enable better soldering. The PCB mother broad thickness is 1
mm ± 0.1 mm; MMI is 0.4 min ± 0.05 mm. All RF components are located on one side of the bottom half area of
the PCB, with the baseband components (Logic circuits) occupying the lower half of the PCB. A metallised shield
shields the RF circuit area. The top half of the back case has been designed to provide a shielded enclosure to
reduce further spurious emissions and logic noise.

Fig 5.2 Transmitter Frequency Generation

– 5–4 –

The CX74017 transmitter functional block diagram is shown in Figure 5.2 The transmit (Tx) chain is based on a
translational loop architecture. The baseband information is injected within the loop therefore the output signal is phase­modulate.

One of the advantages of this architecture is that the Transmit Intermediate Frequency (TxIF) is kept within a narrow
frequency range. This improves phase and amplitude accuracy in the

In-Phase and Quadrature (I/Q) modulator.
The CX74017 has two frequency dividers:

8 D1: set to divide by 9, 10, 11, or 12
8 D2: set to divide by 2 or 1

To minimize the range of the TxIF and the required tuning range of the UHF VCO, the D2 divider is set to /2 mode for low
band operation. Low band operation includes the EGSM. For high band operation, the D2 divider is set to /1 mode.High
band operation includes the DCS1800 .

The UHF VCO is divided by three. After this block, the VCO is multiplied by 1 for low band operation or multiplied by 2 for
high band operation. This block drives both the D1 divider, which feeds the phase detector, and a doubler stage, which
feeds the high side injection down converter 1/2 Local Oscillator (LO) mixer. The mixer mixes the transmit frequency
down to the TxIF frequency that drives the I/Q modulator. The output of the modulator is filtered externally and then fed
back into the CX74017 where it drives the D2 divider. The D2 divider feeds the other input of the phase detector, which
produces an error voltage that is externally filtered. The error voltage tunes the internal Transmit Voltage Controlled

Oscillator (TxVCO).

■ General

RF circuit design is built around and Skyworks CX74017 IC. Other major components include filters, power amplifiers
and the antenna subsystems.

Direct conversion is employed on both receiver bands.
The Tx VCO is on-channel in both E-GSM 900 and GSM 1800 modes of operation.
The RF LO always requires re-tuning between transmit and receive modes, as well as when monitoring adjacent cells.

■ Antenna

The antenna is an internal inverted F-type. It is optimized for both free space and talk positions on GSM 900 and GSM
1800 bands. The RF coaxial connector incorporates a mechanical switch for routing the RF signal to an external
antenna for car kit installations and for test purposes.

■ Transmit and Receive

The transmit and receive paths are covered in their own specific chapters later in this Technical Guide.

The CX74017 transceiver is a highly integrated device for multi-band Global System for Mobile Communications™ (GSM ™)
or General Packet Radio Service (GPRS) applications. The device requires a minimal number of external components to
complete a GSM radio subsystem. The CX74017 supports EGSM900/DCS1800 applications.

The receive path implements a direct down-conversion architecture that eliminates the need for Intermediate Frequency (IF)
components. The CX74017 receiver consists of three integrated Low Noise Amplifiers (LNAs), a quadrature demodulator,
tunable receiver baseband filters, and a DC-offset correction sequencer.

In the transmit path, the device consists of an In-phase and Quadrature (I/Q) modulator within a frequency translation loop
designed to perform frequency up conversion with high output spectral purity. This loop also contains a phase frequency
detector, charge pump, mixer, programmable dividers, and high power transmit Voltage Controlled Oscillators (VCOs) with no
external tank required.

The charge pump output signal produced by the phase detector is fed back to the Tx VCO to generate modulated RF output.
The Tx VCO has been designed to provide a high level output thus obviating the need for a driver amplifier. Therefore, the Tx
VCO output is applied directly to the PA which amplifies the signal to any required level up to PL5 (33 dBm at the antenna) for
E-GSM 900 and PL0 (30 dBm) for GSM 1800. In the same way, the Tx VCO output is applied directly to the PA which
amplifies the signal to any required level up to PL5 (33 dBm at the antenna) for GSM 850 and PL0 (30 dBm) for GSM 1900.

The CX74017 also features an integrated, fully programmable, sigma-delta fractional-N synthesizer suitable for GPRS
multi-slot operation. Except for the loop filter, the frequency synthesizer function, including a wideband VCO, is completely
on-chip.

Table 5.4

Uplink frequencies for the extended part of E-GSM 900 band (975 = ARFCN = 1023) can be calculated as follows:
Uplink frequency = 935 MHz - ((1024 - ARFCN) x 0.2 MHz) e.g. for CH984

935 MHz - ((1024 - 984) x 0.2 MHz)
= 935 MHz - (8 MHz)
= 927 MHz

– 5–10 –

Uplink frequencies for the standard GSM 900 band (0 = ARFCN = 124) can be calculated as follows:
Uplink frequency = 935 MHz + (ARFCN x 0.2 MHz) e.g. for CH55

935 MHz + (55 x 0.2 MHz)
= 935 MHz + (11 MHz)
= 946 MHz

■ GSM 1800

Uplink frequencies for the GSM 1800 band can be calculated as follows:
Uplink frequency = 1805 MHz + ((ARFCN - 511) x 0.2 MHz) e.g. for CH512

1805 MHz + ((512 - 511) x 0. 2MHz)
= 1805 MHz + (0.2 MHz)
= 1805.2 MHz

■ GSM 850

The downlink frequencies for the GSM 850 band are as follows:

Table 5.5

Uplink frequencies for the GSM 850 band (128 = ARFCN = 251) can be calculated as follows:
Uplink frequency = 869 MHz + ((ARFCN - 127) x 0.2 MHz) e.g. for CH185

869 MHz + ((185 - 127) x 0. 2MHz)
= 869 MHz + (11.6 MHz)
= 880.6 MHz
