PBL 403 05
Multiband GSM Power Amplifier
Description.
Key features.
The PBL 403 05 is a dual line-up GaAs MMIC power amplifier intended for use in • One IC handles GSM900, DCS
multiband GSM terminals. Powered of a 3.2V supply it delivers more than 34.5 dBm
1800 and PCS1900 bands.
output power at GSM900 and more than 31.5 dBm output power at DCS1800 or
PCS1900 frequencies.
• Low cost solution.
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 • Inputs matched to 50 Ω
mounting requirements.
The circuit is manufactured in a high performance MESFET process that ensures • Digital band select function.
ruggednes for environmental variations.
• Analog gain control.
• Proven GaAs MESFET-reliability.
• Tape and Reel.
