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 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 performance degradation. The circuit is housed in a specially designed QSOP16 (150 mil body ) package and the implementation requires only few external components.
