  • Ka-band modulator and transmitter
    Patent number: 10374852
    Abstract: The present invention relates to a high data rate Ka-band modulator and transmitter for space applications that functions on the entire NASA Space Network Return Link band of 25.25-27.75 GHz. The modulator is capable of quadrature phase-shift keying (QPSK) modulation and 8-PSK modulation. The transmitter can be designed to provide an adjustable drive to a traveling-wave tube amplifier (TWTA) or transmit power.

  • Spaceflight high data rate radiation hard Ka-band modulator
    Patent number: 8139674
    Abstract: A Ka-band transmitter. The transmitter is in a self-contained module that contains a radio frequency (RF) channel. A phase lock oscillator drives an RF signal path in the RF channel at a fundamental frequency. In-phase data (I-data) and Quadrature data (Q-data) difference signals are converted to single ended signals and filtered in a pair of low pass filters and passed as inputs to a Quadriphase Shift Keying (QPSK) vector modulator in the RF signal path, e.g., an in-line even-harmonic modulator. The output of the QPSK vector modulator, is a Ka-band signal that is passed to a driver which may drive a load, e.g., an antenna.
