introduction

Introduction

ECE 431 – Analog Communication Circuits

(RF Circuit Design)

slide3

Laboratory Project:

AM Broadcast Band Receiver (500-1700 KHz)

Manual and Digital Tuning

Every student builds a radio

Prototyping-style construction method

design problem

Design Problem:

There is too little space on the existing copper-clad board to allow for expansion and experimentation

solution approach

Solution Approach:

Redesign the radio enclosure to accommodate a larger circuit board (or boards)

research

Research

Identify needs and wants

Survey prospective customers

Study existing designs

Brainstorm design alternatives

desired enclosure features

Desired Enclosure Features

Increased circuit board area than the existing design

Easy to manufacture

Low materials cost

Helps with constructing and testing the radio circuits

Low EMI with the outside world

Low EMI between different sections of the radio

Aesthetically pleasing appearance

Sturdy
