Receiving apparatus and method |
摘要 |
<p>A receiving apparatus and method which can prevent second order harmonic interference and beat interference in a direct orthogonal detector is disclosed. When a control signal of the high level is inputted to a control terminal, then a first high frequency switch diode is turned on and a second high frequency switch diode is turned off. In this instance, a filter circuit functions as a low-pass filter. When a control signal of a low level is inputted to the control terminal, then the first high frequency switch diode is turned off and the second high frequency switch diode is turned on. In this instance, the filter circuit functions as a high-pass filter. <IMAGE></p> |
