1 ECEN 5004 (5014) Goals: Learn analog high frequency circuit design, hybrid and monolithic Learn the basic principles that govern high frequency analog circuits Learn some common practices CAD tools: ADS and MWO Evaluation Research like papers, proposal like presentations, conference like reviews Percentage Comment Projects 45% Bi weekly, N p =7 Final exam 25% Closed everything Final project 20% MMIC design and submission for tape out Extra work 10% Participation, lab demos, etc. (to be announced) 1

2 History Who were the most important people for the development of our field? 2

3 The makers of radio The scientists The businessmen James Clark Maxwell ( ) Oliver Heaviside ( ) Heinrich Hertz ( ) Lee DeForest ( ) Edwin Armstrong ( ) Guglielmo Marconi ( ) Nikola Tesla ( ) 3

4 The first radio engineer First Radio Wave Propagation Demonstrations Tesla s first UAV 4

5 Radio changed ship traffic 1909, SS Republic 1700 lives saved 5

6 Radio changed ship traffic 1912, Titanic, Radio call sign: MGY Zoya Popovic, University of Colorado, Boulder,

7 Mobile phones shrunk quickly Bell Labs, 1970s Marconi, 1930s Erickson, 1980s 7

8 Radar 1904, Germany, anti collision in fog (C. Hulsmeyer) 1922 in the US, Navy patent 1935 in the UK Magnetron in 1940 at microwaves (Randall, Boot) Chain home (1937) 25MHz 100kW Freya (1939) 250MHz 20kW 8

9 The wireless world Earth population ~7.6 billion 50 (47.6) mobile phones sold every second! The number of mobile phones exceeded the number of people on planet Earth in October 2014 In 2017, the number of mobile phone subscriptions is the same as the number of people on our planet Economy Apple iphones $50 billion in Q million iphones sold in Q3 of 2017 Nearly 1.5 billion smartphones (Apple and other) sold in 2016 Lifestyle >40% Americans make several calls per hour Energy Telecom is 2% of carbon emission (same as aviation) 9

13 The story of a text message Type message to a friend Your phone modulates the RF carrier (2GHz wave) and transmit through antenna to base station Call routed to backhaul (wired or wireless) Sends message through a fiber by modulating an optical wave Message sent to Wireless Access Point for routing How long does this take? Same process happens in reverse Another base station sends a radio signal to your friend s phone. The friend s phone radio receives the signal, demodulates it and types the message 13
