Abstract
This work presents a heterodyne K/Ka-band transceiver with integrated transmit (Tx)/receive (Rx) calibrator for satellite communication terminal antennas. To reduce the system complexity, the circuit features only three active mixers compared to four in conventional designs, which is also beneficial in terms of power consumption. The signal distribution requires a radio frequency (RF) switch, a local oscillator (LO) diplexer, and a power divider. The transceiver interfaces the back-end circuitry with merely three intermediate frequency (IF) signals and a dual-tone LO signal. Despite the reduced system complexity, it provides full-duplex communication at 20 GHz (Rx) and 30 GHz (Tx) as well as sequential calibration for the Rx and the Tx antennas. The demonstrator realized in standard printed circuit board technology is compact enough to meet phased array requirements and fully verifies the desired functionality.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
