Abstract
A radio frequency receiver front-end includes a low noise amplifier, a mixing stage, and a selectable channel filter. The low noise amplifier is operably coupled to amplify inbound RF signals to produce amplified inbound RF signals. The mixing stage is operably coupled to mix amplified inbound RF signals with a 1local oscillation to produce a 1intermediate frequency (IF) signal. The selectable channel filter is operably coupled to pass a 1channel of the 1IF signal when a channel select signal is in a 1state and to pass a 2channel of the 1IF signal when the channel select signal is in a 2state to produce a selected channel.
