DIRECT DOWNCONVERSION RECEIVER |
摘要 |
A direct downconversion receiver combines a received RF signal and a local oscillator (LO) signal to form a combined signal. The local oscillator signal is also phase-shifted by approximately 90 degrees to form a quadrature signal. A mixer forms the product of the combined signal and the quadrature signal to produce a baseband output signal.
