FUNCTIONAL DESCRIPTION

Operating conditions

The CGY2014ATW is designed to meet the European

Telecommunications Standards Institute (ETSI) GSM

documents, the “ETS 300 577 specification”, which are

defined as follows:

• ton = 570 µs

• T = 4.16 ms

• Duty cycle δ = 1/8.

Multislot operation can be implemented provided that the

application circuit does not drive the IC beyond the limiting

values.

Power amplifier

The GSM and DCS/PCS power amplifiers consist of three

cascaded gain stages with an open-drain configuration.

Each drain has to be loaded externally by an adequate

reactive circuit which also has to be a DC path to the

supply.
