DESCRIPTION
MAS9142 is designed for use in GSM900 and DCS1800 systems, in particular with Hitachi PF08103B power amplifier module. Other PA modules can be used with the MAS9142 with external compensation elements to maintain the stability of the PA control loop. The MAS9142 incorporates the power detector biasing components, RC-filtering for power ramping signal, operational amplifier with AC feedback and a low dropout (LDO) voltage regulator with output voltage 2.8 V and maximum load current of 50 mA for generating supply voltage for VCO/Modulator in the radio channel of a mobile phone.
FEATURES
• Two functional blocks: Power Amplifier Controller and LDO Voltage Regulator
• Low current consumption
• Temperature compensated biasing for externaldetection Schottky diodes
• Both PAC loop and LDO voltage regulator have temperature-controlled power- down feature
• LDO voltage regulator with short circuit current protection
• Excellent ripple rejection in regulatorAPPLICATIONS
• Dual Band Cellular Phone
• PCMCIA GSM/DCS data communications -
