T0701
GSM-GPRS Receiver
Description
The T0701 is a bipolar integrated RF transceiver for GSM-based cellular systems (900/ 1800/ 1900 MHz) and other wireless communication applications. This integrated circuit consists of a superheterodyne receiver with a high 1st intermediate frequency (IF) of 378 MHz and an offset PLL transmitter architecture. Receiver functions include: low-noise pre-amplifier, mixer, digitally controlled gain amplifiers, quadrature demodulator, baseband filters, and baseband amplifiers. Transmitter functions include: I/Q modulator, phase comparator, auxiliary VCO including PLL functions and down-converter. The device is controlled by a 3-wire bus. The T0701 enables to build a small-sized GSM transceiver by adding a single PLL frequency synthesizer (main oscillator), a power amplifier (e.g. TST0911) and few external components. Triple band operation is possible with a 1st IF of 378 MHz and using only a single channel raster VCO with a tuning range of approximately 8.54%. Electrostatic sensitive device. Observe precautions for handling.

Ozone Depleting Substances Policy Statement
It is the policy of Atmel Germany GmbH to 1. Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Atmel Germany GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. Atmel Germany GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances.
