Receiver Analysis Program
Abstract
There are many approaches to the design of microwave receivers. Each approach will use a large number of components with different specifications. It is necessary for the designer to predict the performance of all the designs in order to optimize the receiver, which is a tedious calculation. This report presents a computer program which will do these calculations. The program is basically self-explanatory, since it is written in an interactive conversational mode for on-line execution via an intercom terminal. Questions and explanatory comments are put to the user during execution, which help to guide him in the use of the program. It can be used either through an intercom or batch terminal. The program uses the specification of the receiver components as input, i.e., gain, noise figure, intermod point, etc. The output of the program will not only generate the important characteristics of the receiver, such as sensitivity, dynamic range, and spurious product, but also indicate the elements that limit the performance, by generating the percentage of contribution by each component. One can also easily add a new component to a receiver, eliminate an old one or change the specifications of a component. In case one intends to cover a wider instantaneous bandwidth, for example, in channelized receivers with less hardware, a fold mode can be used. This program can handle the noise figure of the fold mode, provided that the different front ends of the receiver have the same noise figure.
