PBL40309 3.6 V Differential Power Amplifier for DECT Telecommunications system

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 Ω 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 perfo.

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. Key features.
