From a previous blog about low IF receiver we know that it has an image problem as it’s not zero IF anymore so the signal won’t be translated around the baseband so we will have an image problem. In order …
What are the drawbacks of using RC-CR network? RC-CR Network is one of the methods to implement a 90-degree phase shift in a receiver. In this blog, we will discuss the drawbacks of using this method. 1. Image rejection might …
As discussed in the previous blog about the methods to implement 90˚ phase shift, the first method was RC-CR network and second method was quadrature down conversion. In the below figure the architecture of Hartley receiver shows that instead of …
