METHOD AND APPARATUS FOR SELECTIVELY CONFIGURING A TWO-WAY RADIO DEVICE TO OPERATE IN A CONTROL STATION MODE OR A NON-CONTROL STATION MODE

摘要

A method and apparatus for operating a two-way radio device includes a receiver front end that has a low noise amplifier (LNA) and an adjustable attenuator coupled to the output of the LNA. The bias provided to the LNA is adjustable in correspondence with a mode selection of either a control station mode or a non-control station mode of operating the two-way radio device. Since changing the bias level of the LNA changes the gain of the LNA, the adjustable attenuator can be adjusted accordingly to maintain a desired gain level for subsequent portions of the receiver front end.
