PBL 403 05
Multiband GSM Power Amplifier
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.
