I am no expert in the field, but maybe the device named "HackRF" is what you are looking for. It is a low power SDR transceiver with an interface to GNU radio, and, with a 20 Ms/s sampling (if I remember correctly - don't have the data sheet here) rate, the baseband should be broad enough for generating a QPSK signal in the Mbit/s range...
