PRELIMINARY
ML2731 PA Bias Controller
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.
