| description | A dual rate transmitter may include a modulator circuit configured to modulate orthogonal signals to generate a quadrature modulated signal. An amplifier may be configured to amplify the quadrature modulated signal to produce an amplified signal. A quadrature partial response (QPR) filter may be configured to process the amplified signal to generate an output signal. The QPR filter may allow for full rate QPR and half rate QPSK operation of the transmitter device. The output signal may be transmitted via an antenna. This transmitter approach provides a bandwidth efficiency improvement, as the QPR signal may be operated at twice the rate within the same bandwidth as the quadrature modulated signal using a common saturated transmitter implementation, reducing quantity of components and the resulting mass and cost reduction for a space transmitter solution. Additionally, this approach of using QPR signaling provides greater power efficiency. |
