Research on the Intermediate Frequency Receiver of L-Band

With the rapid development of wireless communications, there are more and more ​​stringent requirements on the wireless receiver, such as low power consumption, high reliability, low price, as well as smaller size. The design of RF receiver is the key to achieve this goal. According to the actual needs of the project, a double conversion IF receiver is designed. At first, the high frequency signal is changed to a higher IF, and the second output is a zero-IF signal. Experimental results show that the receiver has 100dB gain and a flat bandwidth.
