ML2731 Datasheet (Micro Linear) - PA Bias Controller

ML2731, PA Bias Controller

The ML2731 is a power amplifier (PA) bias controller with support circuits for a typical radio transceiver.

The IC integrates a PA bias controller, a PA DC switch, a crystal oscillator circuit, a negative voltage generator and two voltage regulators.

It can be used with GaAs FETs and silicon bipolar
