PBL 403 09

3.6 V Differential Power Amplifier

for DECT Telecommunications system

Description.

Key features.

The PBL 403 09 is a differential two stage silicon MMIC power amplifier intended for • 27 dBm output power

use in handheld cordless terminals in the 1900 MHz band. It can deliver more than 27

dBm at 1900 MHz into a balanced 50 Ω load using a single 3.6 V supply. The circuit has • 25 dB small signal gain

a logic input to control transmit on/off and can be operated up to 100 % duty cycle with

minimum performance degradation. The circuit is housed in a specially designed • 50 % Power Added Efficiency

QSOP16 (150 mil body ) package and the implementation requires only few external

components.

• Simple logic on/off power control

25 GHz ft state-of-the-art deep trench isolated double-poly silicon bipolar process

with additional features for improved wireless performance has been used. On-chip • Battery charging conditions to 5.0 V

capacitors and inductors are used for the integrated internal matching network. Special

front-side metallized substrate contacts provide excellent ground paths from active • ESD protected

devices to the highly doped semiconductor substrate and package ground.

• Excellent ruggedness

• On-chip input and interstage

matching

• Differential input matched to 50 Ω

• Easy implementation with a simple

output matching network
