Rydberg microwave electrometry has attracted great attention, due to its potential application in radar and communication, but simultaneously achieving high sensitivity and broad instantaneous bandwidth remains a challenge. This study demonstrates an enhanced instantaneous bandwidth of ±{}10.2 MHz with sensitivity of 62 nV cm^-1 Hz^-1/2 by the amplification of one sideband wave in the six-wave-mixing process of a Rydberg superheterodyne receiver.
