HC25 Hardware Interface Overview1.5 Safety Precautions12sHC25_HO_v00.220 Page 12 of 39 2007-03-20Confidential / Preliminary1.5 Safety PrecautionsThe following safety precautions must be observed during all phases of the operation, usage,service or repair of any cellular terminal or mobile incorporating HC25. Manufacturers of thecellular terminal are advised to convey the following safety information to users and operatingpersonnel and to incorporate these guidelines into all manuals supplied with the product. Fail-ure to comply with these precautions violates safety standards of design, manufacture andintended use of the product. Siemens AG assumes no liability for customer’s failure to complywith these precautions.When in a hospital or other health care facility, observe the restrictions on the use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guide-lines posted in sensitive areas. Medical equipment may be sensitive to RF energy.The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufac-turer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it can-not be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both.Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electri-cal equipment in potentially explosive atmospheres can constitute a safety hazard.Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger.Road safety comes first! Do not use a hand-held cellular terminal or mobile when driv-ing a vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile, park the vehicle. Speakerphones must be installed by qualified personnel. Faulty installation or opera-tion can constitute a safety hazard.IMPORTANT!Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential com-munications, for example emergency calls. Remember, in order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call.Some networks require that a valid SIM card be properly inserted in the cellular termi-nal or mobile.

HC25 Hardware Interface Overview4 Antenna Interface22sHC25_HO_v00.220 Page 17 of 39 2007-03-20Confidential / Preliminary4 Antenna InterfaceThe RF interface has an impedance of 50Ω. HC25 is capable of sustaining a total mismatch atthe antenna connector or pad without any damage, even when transmitting at maximum RFpower. The external antenna must be matched properly to achieve best performance regarding radi-ated power, DC-power consumption, modulation accuracy and harmonic suppression.Antenna matching networks are not included on the HC25 PCB and should be placed in thehost application. Regarding the return loss HC25 provides the following values in the active band:The connection of the antenna or other equipment must be decoupled from DC voltage. Thisis necessary because the antenna connector is DC coupled to ground via an inductor for ESDprotection. Note: The antenna must be isolated for ESD protection (to withstand a voltage resistance upto 8kV air discharge).4.1 Antenna InstallationTo suit the physical design of individual applications HC25 offers two alternative approachesto connecting the antenna: • Recommended approach: U.FL-R-SMT antenna connector from Hirose assembled on thetop side of the PCB. See Section 4.3 for connector details.• Antenna pad and grounding plane placed on the bottom side. See Section 4.2.The U.FL-R-SMT connector has been chosen as antenna reference point (ARP) for the Sie-mens reference equipment submitted to type approve HC25. All RF data specified throughoutthis manual are related to the ARP. IMPORTANT: Both solutions can only be applied alternatively. This means, whenever anantenna is plugged to the Hirose connector, the pad must not be used. Vice versa, if theantenna is connected to the pad, then the Hirose connector must be left empty.

HC25 Hardware Interface Overview4.2 Antenna Pad22sHC25_HO_v00.220 Page 18 of 39 2007-03-20Confidential / PreliminaryNo matter which option you choose, ensure that the antenna pad does not come into contactwith the holding device or any other components of the host application. It needs to be sur-rounded by a restricted area filled with air, which must also be reserved 1.4mm in height.Figure 1: Restricted area around antenna pad (side and bottom view)4.2 Antenna PadThe antenna can be attached via contact springs.If you decide to use the antenna pad take into account that the pad has not been intended asantenna reference point (ARP) for the Siemens HC25 type approval. The antenna pad is pro-vided only as an alternative option which can be used, for example, if the recommended Hiroseconnection does not fit into your antenna design. Also, consider that according to the GSM recommendations TS 45.005 and TS 51.010-01 a50Ω connector is mandatory for type approval measurements. This requires GSM devices withan integral antenna to be temporarily equipped with a suitable connector or a low loss RF cablewith adapter.

HC25 Hardware Interface Overview6.2 Mounting HC25 to the Application Platform30sHC25_HO_v00.220 Page 29 of 39 2007-03-20Confidential / Preliminary6.2 Mounting HC25 to the Application PlatformThere are many ways to properly install HC25 in the host device. An efficient approach is tomount the HC25 PCB to a frame, plate, rack or chassis. Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customizedscrews, clamps, or brackets. In addition, the board-to-board connection can also be utilized toachieve better support. To help you find appropriate spacers a list of selected screws and dis-tance sleeves for 3mm stacking height can be found in Section 8.2.When using the holes the screws can be inserted from top or bottom. For proper grounding it is strongly recommended to use the large ground plane on the bottomof board in addition to the five GND pins of the board-to-board connector. The ground planemay also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape.Please take care that attached cooling elements do not touch the antenna pads on the mod-ule’s bottom side, as this may lead a short-circuit. To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it ispositioned flat against the host device (see also Section 8.3 with mounting advice sheet).6.3 Board-to-Board Application ConnectorThis section provides specifications for the 50-pin board-to-board (B2B) connector used to con-nect HC25 to the host application.
