2General Information
After the S6 PCN and the S6 Power PCN, the S11 is the third model of the new
handset generation for GSM-1800 in 3 Volt technology. Mechanically and technically
it is very similar to the S10.
In addition to the normal S11 another version called S11 E is available which offers
Enhanced Fullrate speech coding to improve the speech quality.
3Mechanical Concept
Note: All part numbers refer to mechanical drawing in section 4.1!
The S11 consists of two boards, the RF & Control module (1000) and the user
interface (1010).
The connection between those two boards is made by a normal connector with plug-
in contacts.
The RF connection from the display module to the RF & Control module is made by
an RF cable (1150) which is soldered onto to RF & Control module, which is covered
by two shieldings (1060, 1050).
The antenna (1130) is directly screwed into the lower case shell.

The keypad (1020), the loudspeaker (1120), the microphone (1110), the dust
protection frame (1190) and the microphone gasket (1220) are mounted into the
upper case shell (1030). Make sure that the microphone contacts are properly bent
up when mounting.
When turning in the screws (1070, 1080) make sure that the right torque is used (25
Ncm), because this will have an effect on the funtionality of the handset.
The only removable part on the user interface is the ringer gasket (1170) which is
needed to increase the ringer volume.

3.4Handset Datecodes
Siemens is using the industrial standard IN EN 60062 to indicate the production /
service dates. The code is printed on the IMEI sticker located under the simcard
reader.

The first character of the datecode indicates the year of production:
F = 1995
H = 1996
J = 1997
K = 1998
The second character indicates the month of production:
1-9 = January to September
O = October

HiGOL (PMB 2800)

Private Communication Systems
Mobile Phones
4.2Hardware Description
The S11 handset consists of five major integrated circuits:
1) HiGOL (PMB 2800)
This IC is a combination of microprocessor and signalprocessor.
The microprocessor is responsible for controlling the keyboard, SIM-Card, EEPROM,
Flash and RAM.
Furthermore it controls the power up/power down of the RF module and sets the
amplification of the PA.
The signal processor is responsible for processing the Rx I/Q signals (filtering,
equalizing, speech and channel decoding).
Furthermore it does the speech and channel encoding and the GSMK modulation of
the Tx I/Q signals.
3) GAIM (PMB 2905)
The GAIM (GSM Analogue Interface Module) provides the interface between the
analogue signals (I/Q, voiceband, PA-control) and its digital representation.
4) Receiver Circuit (PMB 2405/07)
This circuit provides the following main functionalities:
a) Low Noise Amplifier (LNA) with a fixed amplification of +20dB to amplify the input
RF signal.
b) Mixer to mix down the RF signal to the Intermediate Frequency (IF)
c) Programmable IF amplifier with a dynamic range of 60dB ( -10dB ... +50dB in
steps of 2dB)
d) Mixer to mix down the IF signal to the baseband, generating and inphase (I) and a
quadrature (Q) signal.
e) Offset compensation for the I/Q signals.
5) Transmitter Circuit PMB 2240/45
This circuit provides the IF synthesizer, the I/Q modulator, prescalers to regulate the
RF synthesizer and a buffer stage to feed the PA.
The antenna switch is electrical, controlled by a signal at the bottom connector.

4.3Power S pply Concept
The S11 has two main power inputs (see Blockdiagram):
1) Battery Voltage (3.6 Volts) connected at the battery contacts
2) Charging Voltage (6.5 Volts) delivered by
a) The plug-in charger at the charging plug
b) The desktop charger using the charging contacts at the bottom of the phone
c) The car kit using the charging connection at the bottom of teh phone
Since the battery voltage is supplying the power supply asic, it is always needed to
operate the phone. You cannot switch on the handset if the battery voltage is not
present.
From the 3.6 V battery voltage, all other supply voltages of the S11 are derived,
controlled by the power supply ASIC.
The VCC_ voltage is used to supply external accessories through the bottom
connector.
The RF module needs 6.0 V for its PA, this voltage is generated by a step-up
converter.
The logic module uses 2.8 V, generated by a simple linear regulator.

Furthermore the ASIC generates the supply voltage for the SIM-Card and the
RESET signal for the logic devices.
The ASIC also checks the presence of the watchdog signal from the µP and provides
the switching on functionality (ON_OFF button or Ignition signal).
uring testing ist is advisable to use a battery dummy, connected to a power supply
delivering +4V, max 3A.
Make sure that you connect the battery dummy with the right polarity, the red plug to
+4V and the blue plug to ground.
If yo se a voltage higher than +7V, or with wrong polarity, the phone can be
destroyed!
4.4Critical Conditions
a) Battery Voltage:
If the battery voltages rises above 6.2 Volts, the phone will switch off and it cannot
be switched on again before the voltage drops below 6.2 Volts.
If the battery voltage rises above 7 Volts the phone can be destroyed.
b) Battery Charging Current:
The charging current must not rise above 1 A or the phone (fuse) will be inoperable.
-> Be careful with foreign accessories or chargers!
-> Make sure that the charging current is limited to a value
below 1A!
c) Supply Current for External Accessories:
If you use accessories that are supplied through the bottom connector of the
handset, make sure that the accessory does not draw more than 250 mA.
Otherwise a 0.25 A fuse will blow.
5Software programming
The software of the S11 handsets is programmed directly from a PC using the
bootadapter (see drawing below).

Private Communication Systems
Mobile Phones
If the phone is disabled due to a wrong entry of the phonecode (not PIN1, PIN2,
network code or service provider code!) it can only be reset by entering the right
unblocking code.
The unblocking code is derived from the IMEI number and can only be calculated by
our hotline personell in Germany.
If you need unblocking codes just send a fax with the IMEI numbers to:
Siemens AG
PN KE SH
World Service Center
Bocholt, Germany
Fax: [phone]
Please use the appropriate form provided by your service coordinator!
As an alternative, from november of 1997 on, an internet solution is offered.
This will be a password protected internet homepage where you can enter the IMEI
number of the affected handset. The page will then present Master Phone Codes,
Master Network Codes and Master Service Provider Codes if applicable.
Contact your service manager for details.
