1. INTRODUCTION

1.1 Purpose

This manual provides the information necessary to repair, calibration, description and download the features

of this model.

1.2 Regulatory Information

A. Security

Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example,

persons other than your company’s employees, agents, subcontractors, or person working on your

company’s behalf) can result in substantial additional charges for your telecommunications services.

System users are responsible for the security of own system. There are may be risks of toll fraud associated

with your telecommunications system. System users are responsible for programming and configuring the

equipment to prevent unauthorized use. The manufacturer does not warrant that this product is immune

from the above case but will prevent unauthorized use of common carrier telecommunication service of

facilities accessed through or connected to it. The manufacturer will not be responsible for any charges that

result from such unauthorized use.

B. Incidence of Harm

If a telephone company determines that the equipment provided to customer is faulty and possibly causing

harm or interruption in service to the telephone network, it should disconnect telephone service until repair

can be done. A telephone company may temporarily disconnect service as long as repair is not done.

C. Changes in Service

A local telephone company may make changes in its communications facilities or procedure. If these

changes could reasonably be expected to affect the use of the phones or compatibility with the net work, the

telephone company is required to give advanced written notice to the user, allowing the user to take

appropriate steps to maintain telephone service.

D. Maintenance Limitations

Maintenance limitations on the phones must be performed only by the manufacturer or its authorized agent.

The user may not make any changes and/or repairs expect as specifically noted in this manual. Therefore,

note that unauthorized alternations or repair may affect the regulatory status of the system and may void

any remaining warranty.

E. Notice of Radiated Emissions

This model complies with rules regarding radiation and radio frequency emission as defined by local

regulatory agencies. In accordance with these agencies, you may be required to provide information such as

the following to the end user.

F. Pictures

The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly different.

G. Interference and Attenuation

A phone may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from

unsuppressed engines or electric motors may cause problems.

H. Electrostatic Sensitive Devices

ATTENTION

Boards, which contain Electrostatic Sensitive Device (ESD), are indicated by the sign.

Following information is ESD handling:

• Service personnel should ground themselves by using a wrist strap when exchange system boards. • When

repairs are made to a system board, they should spread the floor with anti-static mat which is also grounded.

• Use a suitable, grounded soldering iron. • Keep sensitive parts in these protective packages until these are

used.

• When returning system boards or parts like EEPROM to the factory, use the protective package as described.

3.1 GENERAL DESCRIPTION

The E510f supports UMTS-850, UMTS-2100, GSM-850, GSM-850, GSM-900, GSM-1800, and GSM-1900 based

GSM/GPRS/EDGE/UMTS. All receivers and the UMTS transmitter use the radioOne1 Zero-IF architecture to

eliminate intermediate frequencies, directly converting signals between RF and baseband. The quad-band

GSM transmitters use a baseband-to-IF upconversion followed by an offset phase-locked loop that translates

the GMSK-modulated or 8-PSK-modulated signal to RF.

A generic, high-level functional block diagram of E510f is shown in Figure 1-1. One antenna collects base

station forward link signals and radiates handset reverse link signals. The antenna connects with receive and

transmit paths through a FSM(Front-End-Module).

The UMTS receive paths each include an LNA, an RF band-pass filter, and a downconverter that translate the

signal directly from RF-to-baseband using radioOne ZIF techniques. The RFIC’s Rx analog baseband outputs,

for the receive chains, connect to the MSM IC. The UMTS and GSM Rx baseband outputs share the same

inputs to the MSM IC.

For the transmit chains, the RTR6285 IC directly translates the Tx baseband signals (from the MSM device) to

an RF signal using an internal LO generated by integrated onchip PLL and VCO. The RTR6285 IC outputs

deliver fairly high-level RF signals that are first filtered by Tx SAWs and then amplified by their respective

UMTS PAs. In the GSM receive path, the received RF signals are applied through their band-pass filters and

down-converted directly to baseband in the RTR6285 transceiver IC. These baseband outputs are shared with

the UMTS receiver and routed to the MSM IC for further signal processing.

The GSM/EDGE transmit path employs one stage of up-conversion and, in order to improve efficiency, is

divided into phase and amplitude components to produce an open-loop Polar topology:

1. The on-chip quadrature up-converter translates the GMSK-modulated signal or 8-PSK modulated signal, to

a constant envelope phase signal at RF;

2. The amplitude-modulated (AM) component is applied to the ramping control pin of Polar power amplifier

from a DAC within the MSM. E510f power supply voltages are managed and regulated by the PM7540 Power

Management IC. This versatile device integrates all wireless handset power management, general

housekeeping, and user interface support functions into a single mixed signal IC.

It monitors and controls the external power source and coordinates battery recharging while maintaining the

handset supply voltages using low dropout, programmable regulators.

The device’s general housekeeping functions include an ADC and analog multiplexer circuit for monitoring

on-chip voltage sources, charging status, and current flow, as well as user-defined off-chip variables such as

temperature, RF output power, and battery ID.

Various oscillator, clock, and counter circuits support IC and higher-level handset functions. Key parameters

such as under-voltage lockout and crystal oscillator signal presence are monitored to protect against

detrimental conditions.
