Description.
The PBL 403 05 is a dual line-up GaAs MMIC power amplifier intended for use in multiband GSM terminals. Powered of a 3.2V supply it delivers more than 34.5 dBm output power at GSM900 and more than 31.5 dBm output power at DCS1800 or PCS1900 frequencies.
The circuit uses an analog control signal to control the output power level. The circuit is housed in a specially designed QSOP28 (150 mil body) package with no special mounting requirements.
The circuit is manufactured in a high performance MESFET process that ensures ruggednes for environmental variations.
