摘要： The disclosure provided a low noise block converter for converting RF signal received from a satellite into IF signal, where the image rejection of the RF signal is performed in two stages through a low noise amplifier (LNA) integrated circuit (IC). The disclosure reduced the number of discrete components by integrating electronic components onto one integrated circuit (or chip), and at the same, improves the noise figure of the LNB converter. The LNB IC comprises LNA circuits, RF path selector, and signal downconverter, where the image rejection is performed by a combination of the LNA circuits and the signal downconverter.

摘要： The invention provides a circuit structure sharing the same memory, where the circuit structure includes a first volatile memory, a system chip and a signal processing chip. The system chip is connected to the first volatile memory via a first connection interface. The signal processing chip is connected to the system chip via a second connection interface. A memory controller is disposed in the system chip and connected to the first connection interface and the second connection interface. The signal processing chip transmits a first access command to the memory controller via the second connection interface, and the memory controller accesses the first volatile memory via the first connection interface according to the first access command and transmits the access result of the first access command to the signal processing chip via the second connection interface.
