 技術摘要： |
A radio frequency transmitting device includes a frequency multiplier circuit, a mixer circuit, a power splitter, a plurality of phase shifting circuits, a plurality of amplifiers, and a plurality of antennas. The frequency multiplier circuit is configured to amplify a fundamental signal to generate a harmonic signal. The mixer circuit is configured to generate a RF signal based on an input signal and the harmonic signal. The power splitter is configured to generate a plurality of sub-RF signals. The phase shifting circuits are configured to shift the phase of the sub-RF signals. The amplifiers are configured to amplify the power of the sub-RF signals. The antennas are configured to transmit the sub-RF signals. Furthermore, a radio frequency receiving device is also disclosed herein.
