PBL 403 10
3.5 V GSM 900 MHz Power Amplifier
The PBL 40310 is a highly integrated single-ended silicon MMIC power amplifier • 2.7 to 5.0 V single supply operation
intended for use in GSM terminals. It delivers 35 dBm at 900 MHz with 55 % power added
efficiency into a 50 Ω unbalanced load using a single 3.5 V supply.
• 35 dBm output power at 3.5 V
The circuit has an analog ramp signal to control output power level and a logical on/
off signal for power down mode. It can be used in dual-band amplifiers using the band • 55 % Power Added Efficiency
select logical signal. It can be operated up to 50 % duty cycle with minimum performance
degradation. The circuit is housed in a specially designed QSOP16 (150 mil body) • Input matched to 50 Ω
package and the implementation requires only few external components.
25 GHz ft state-of-the-art deep trench isolated double-poly silicon bipolar process • Complete on chip input and
with additional features for improved wireless performance has been used. On-chip
capacitors and inductors are used for the integrated internal matching network. Special
front-side metallized substrate contacts provide excellent ground paths from active • Analog power control
devices to the highly doped semiconductor substrate and package ground.
• Less than 10 µA current
consumption in power down mode
• Proven RF Silicon Technology
• Minimum number of external
components for low overall solution
