1.2.1 RF functionalities
The Radio Frequency (RF) functionalities comply with the Phase II EGSM
900/GSM 1800 and GSM 850/GSM 1900 recommendation. The frequencies
are :
Q2406
Rx (EGSM 900): 925 to 960 MHz Rx (GSM 1800): 1805 to 1880 MHz
Tx (EGSM 900): 880 to 915 MHz Tx (GSM 1800): 1710 to 1785 MHz
Q2426
Rx (EGSM 850) : 869 to 894 MHz Rx (GSM 1900) : 1930 to 1990 MHz
Tx (EGSM 850) : 824 to 849 MHz Tx (GSM 1900) : 1850 to 1910 MHz
The Radio Frequency (RF) part is based on a specific dual band chip including :
Low-if Receiver
Dual RF (Radio Frequency) synthesizer
Digital if to Baseband Converter
Offset PLL (Phase Lock Loop) transmitter
1 (logarithmic) Power Amplifier (PA) controller
Dual band (Power Amplifier (PA) module
1.2.2 Baseband functionalities
The digital part of the WISMO Quik Q24x6 Series is composed of a PHILIPS-
VLSI chip (ONE C GSM/GPRS Kernel). This chipset is using a 0,25 μm mixed
technology CMOS, which allows massive integration as well as low current
consumption.
1.3 Firmware
WISMO Quik Q24x6 Series is designed to be integrated into various types of
applications
such
as handsets
or
multimedia,…).
vertical
applications
(telemetry,
For vertical applications, the firmware offers a set of AT commands to control
the module.
With this standard software, some interfaces of the module are
not available
since they are dependent on the peripheral devices connected to
the module. They are the LCD interface and the SPI bus.
