PBL40309

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. PBL40309 can deliver more than 27 dBm at 1900 MHz into a balanced 50 W 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 PBL40309 is housed in a specially designed QSOP16 (150 mil body ) package and the implementation requires only few external components.

25 GHz ft state-of-the-art deep trench isolated double-poly silicon bipolar process with additional features of PBL40309 for improved wireless performance has been used. On-chip capacitors of PBL40309 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.
