ML2731 General Description
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 devices.
Micro Linear's ML2731, along with the ML2712 and the ML2713, form a complete transceiver solution for the 2.4 GHz IEEE802.11 communication standard, as well as other wireless ISM communication products.
In addition to supporting Micro Linear's transceiver chip set, the ML2731 can stand alone as: A compact bias voltage controller A compact negative voltage generator A compact crystal oscillator
