摘要： System and method for signal modulation. In one embodiment, a circuit includes a channel for carrying an analog RF signal, a phase offset circuit on the channel, and configured to receive a phase code for modifying the analog RF signal to produce a modified RF signal, and a feedforward cancellation path coupled in parallel to the phase offset circuit for canceling a portion of the modified analog signal.

摘要： The present disclosure is directed towards an analog beamformer multiple beam feed (MBF). The analog beamformer MBF comprises a plurality of encoder elements to receive radiofrequency (RF) signals and generate coded analog signals. The RF signals may be coded using code division multiple access (CDMA) codes. The analog beamformer MBF further comprises a combiner to combine the coded analog signals received from the plurality of encoder elements and a divider to receive the combined coded analog signals and generate a plurality of coded analog outputs. The analog beamformer MBF further comprises a plurality of decoder elements to receive the plurality of coded analog outputs and generate decoded analog signals. In some embodiments, the RF signals may be decoded using CDMA codes. The analog beamformer MBF further comprises a plurality of beamformer elements configured to generate beam outputs corresponding to the decoded analog signals.
摘要翻译：本公开涉及模拟波束成形器多波束馈送（MBF）。模拟波束形成器MBF包括多个编码器元件，用于接收射频（RF）信号并生成编码的模拟信号。 RF信号可以使用码分多址（CDMA）码来编码。模拟波束形成器MBF进一步包括组合器，用于组合从多个编码器元件接收到的编码模拟信号和分配器以接收组合的编码模拟信号并生成多个编码模拟输出。模拟波束形成器MBF还包括多个解码器元件，以接收多个编码模拟输出并生成解码模拟信号。在一些实施例中，可以使用CDMA码对RF信号进行解码。模拟波束形成器MBF还包括多个波束形成器元件，其被配置为生成对应于解码的模拟信号的波束输出。
