The GT-Y3400 module supports receiver diversity. Both require a secondary antenna
connection. The antenna connectors can be identified by the letters “M” for the main antenna
and “D” for the Diversity, printed on the PCB.

2.1.6 Installation restrictions and RF Exposure information
The installation of this module is limited to installation by Samsung Electronics IT Company. The
antenna gain used with this module must not exceed 1.4dBi in the 850MHz Cellular band and
1dBi in the 1900MHz PCS Band when it is integrated. This device is approved for use with the
following antenna (or equivalent):
Four S Tech Model: CDMA-DUAL WLL ANTENNA
Type: Dipole Antenna
Bands: CDMA 800MHz, 1900MHz, WCDMA 2.1GHz
RF Exposure – Critical Installation Requirements:
This device is approved for use as a mobile installation meaning that it will only be used in
products that are capable of maintaining a minimum separation distance of 20cm from the
antenna(s) of this device and the end user.
When installed in a final configuration the antenna must be installed such that a minimum
separation of 20 cm (8 inches) between the wireless device and the body of the user (this does
not include extremities) must be maintained during use and while the wireless device is on and
transmitting. This distance must be ensured for all operating modes and conditions.
This transmitter must not be collocated or operate in conjunction with any other antenna or
transmitter.
Installations in which the device is collocated with other transmitters or the minimum separation
distance between the body and antenna(s) can not be maintained require a separate FCC
authorization. Such installations may require additional testing for RF Exposure (i.e. SAR) and a
Class II Permissive Change filing for FCC approval. Please contact Samsung Electronics, Ltd.
regarding such installations.
Labeling:
The host equipment into which the module is installed must be clearly labeled with the FCC
identifier of the module. This label must be permanently installed and can not be placed on a
removable cover or part such as a battery cover. The label must be similar to the following:
Contains FCC ID: A3LGTY3400
Warning:
Any changes or modification to said product not expressly approved by Intel could void the user’s
authority to operate this device.

50 ± Normal
2.2.1 Measuring Method
The impedance over the frequency bands shall be as close as possible to
50 after matching. Both free space and talk position are considered.
2.3 VSWR
The impedance matching should be optimized in the more critical talk
position.

2.3.2 Measuring Method
A 50 coaxial cable is connected(soldered) to the 50 point, at the duplex-
filter on the main PCB. The connection of the coaxial cable shall be done to
introduce a minimum of mismatch. As much as possible the coaxial cable
arrangement shall prevent influences from induced currents on the cable.
In the other end, the coaxial cable is connected to a network analyzer.
The measurement is performed at room temperature. The handset,
including the PCB, must not in any significant way differ from the mass
production, i.e. the antenna feeding network has to be equivalent to the
feeding network in mass production. The specification shall be met in the
entire frequency band.
