PBL 403 09
3.6 V Differential Power Amplifier
for DECT Telecommunications system
Description.
The PBL 403 09 is a differential two stage silicon MMIC power amplifier intended for
use in handheld cordless terminals in the 1900 MHz band. It can deliver more than 27
dBm at 1900 MHz into a balanced 50
鈩?/div>
load using a single 3.6 V supply. The circuit has
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
QSOP16 (150 mil body ) package and the implementation requires only few external
components.
25 GHz f
t
state-of-the-art deep trench isolated double-poly silicon bipolar process
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
devices to the highly doped semiconductor substrate and package ground.
