摘要:
Exemplary embodiment are directed to preserving transmitter linearity in RF transceivers while reducing RX band noise for use with low-power voltage supplies. In one aspect, a programmable attenuation element may be provided on-chip at the output of a driver amplifier, prior to a matching network. In another aspect, the programmable attenuation element may include a plurality of switchable capacitors.
