market, and further testing may be required, with this module installed in the host device.
Compliance with FCC/IC Rules and Regulations
This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does
not cause harmful interference, and that this device must accept any interference received, including
interference that may cause undesired operation.
Caution
Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate
the equipment.
When incorporating the 80350 module in a host product, the integrator must ensure that the host product
comply with relevant FCC requirements and regulations.
For mobile or fixed applications (with the device at least 20 cm or 7.9 in. distance from the body), the integrator
is authorized to use the FCC/IC Grants and Certificates of this module for their host product if the module is
integrated and installed in accordance with the conditions under which the module has been tested and
certified. In this case the FCC label of the module shall be visible from the outside, or the host product shall bear
a label making reference to the module inside (the label should state “Contains FCC ID JUP80350000A” or
something to the effect). FCC RF safety regulations require a warning label prompting the user to keep the
antenna of a device in operation at least 20 cm or 7.9 in. distance from the body.

1.5 General Design Guidelines
1.5.1 Advanced tips for an RF friendly layout
1.5.1.1 Ground Plane
When designing the 80350 module into the host application, special care must be taken regarding the design of
grounding on the host PCB. Proper grounding of the module’ is an essential part of any good application, as it
can very effectively keep EMI in check and ensure good heat dissipation. An example is shown in the drawing
below:
1． It is recommended that the entire board space underneath the 80350 module be made the ground plate
with sufficient ground vias, and this ground be adequately connected to the mounting tab ground. In doing
so, good connectivity can be achieved between the module’s ground and that of the host board.
2． Running traces beneath this ground plate is strongly discouraged.
11/10/2008 Confidential Page 11 of 53
80350 Module Integration Guide
1.5.1.2 Antenna and RF Signal Trace
For best antenna performance, please ensure that the antenna’s RF trace be designed to be 50 ohm special
impedance line, and that there are a sufficient number of ground holes around the antenna impedance line and
connector. Keep other traces of the module and the host board as far from this impedance line as possible. It
should be avoided that other traces run in parallel to or cross the antenna impedance line. The antenna should
be kept away metallic components.
1.5.1.3 Vbatt Input
The power supply of the 80350 module is of critical importance to the module’s stability and safety. The 80350
module encompasses all working elements of GSM. It is recommended that the width of power trace be greater
than 2 mm, and that a sufficiently large capacitor be placed in the nearest vicinity of the Power pin (two 1000uF
capacitors, preferably, low ESR Tantalum capacitors) in order to cope with bursts during GSM operation (such
bursts cause voltage transients as shown in the figure below).
11/10/2008 Confidential Page 12 of 53
80350 Module Integration Guide
The following picture shows an example of the power supply trace for the module. The trace covers the entire
power pin of the module. The wide trace is intended to minimize voltage drop over the trace.

80350 Module Integration Guide
1.5.2 Audio Reference Design
1.5.2.1 Audio schematics
The audio quality is very much dependent on the circuit design and layout. As an aid to obtaining good audio
quality, a reference design has been included below.
1． Please serially place a Bead on Audio In/Out (see in the following circuit: L100, L101, L102, L103, L106 and
L107) in order to reduce GSM TDD noise. Bead (100MHz, R>=1K ohm) is recommended.
2． Add a small capacitor on each audio trace. This small capacitor is for further reducing the TDD noise. The
typical value of capacitance is 10pF to 100pF. The actually value needs to be tuned based on the location
and layout of the audio circuitry.
3． The suggested locations of the capacitors and Bead are in the vicinity of Microphone and Receiver, rather
than the module.
4． Maintain proper separation of the Audio In reference ground from the Audio Out reference ground so as to
minimize ECHO coupling in the circuitry.
5． Microphone and Receiver should be physically separated from one another, e.g., on the two far ends of the
evaluation board, as the spatial coupling of voice signal may occur, resulting in ECHO or screeching sound.
11/10/2008 Confidential Page 14 of 53
80350 Module Integration Guide
1.5.2.2 Audio Layout
Audio signals are very weak and are in the category of weak analog signals; they are extremely susceptible to
interference from digital signals. Therefore, it is suggested that audio signal traces follow the same layer
differential trace layout method, and be kept far away from strong digital signals (e.g., power signal, RF related
signal, CLK signal and high-speed Bus).
