Description
T0345 is a monolithic integrated circuit, realised using Atmel Wireless & Microcontrollers advanced silicon germanium bipolar SiGe technology. Its RF performance meets the requirements for products designed to IS-95/98 standards. It incorporates the complete transmitter chain for dual-band triple-mode cellular phones supporting CDMA (IS95) in cellular and PCS bands as well as AMPS. The device integrates an I/Q modulator, variable gain amplifier (VGA), two single side-band up-conversion mixer with fully integrated LO phase shifters, a voltage-controlled oscillator (VCO). Furthermore it includes a complete PLL with dividers, phase-frequency detector (PFD) and a charge pump. T0345 provides programmable output power in cellular and PCS band. The IC is available in a small leadless micro lead frame outline 32-pin (MLF32) package.

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.
