Description

The GSM Analog Interfacing Module (GAIM)PMB2905 is part of a chip set, which covers all functions of a mobile radio provided for the Global System for Mobile communications, GSM. A mobile terminal which contains PMB2905 will meet all performance requirements set down in the GSM recommendations for speech and data services.

GAIM PMB2905 is provided for analog-to-digital and digital-to-analog conversion of baseband and voiceband signals as well.Moreover digital-to-analog conversion of an RF power control signal can be performed by this circuit.
