Fall, period 2

Learning outcomes 

1. learns key components of radio transceivers used in wireless communications including LTE and 5G.

2. knows different kind of impedance matching methods and can design the impedance matching network using lumped components and microstrip lines.
A student can also explain factors, which are limiting the bandwidth of impedance matching networks. Smith chart (admittance/impedance chart).

3. will be able to design a low noise RF amplifier. The amplifier is designed that the noise figure is minimized or the gain is maximized. The impedance matching can also be made for the constant gain.

4. knows single sideband and double sideband noise in mixers. A student will be able to design balanced and double balanced mixer and knows the advantages and the disadvantages of these mixers.

5. will be able to design passive microwave components like a Wilkinson power divider, a directional coupler and hybrids.

6. can explain basic priciples of RF-oscillators. A student can design a cross-coupled oscillator and voltage controlled oscillator.

7. knows concept of noise, non-linearity and dynamic range as used in radio frequency communications.

8. can classify power amplifiers and will be able in the basic case design the matching network for a power amplifier.


Noise, non-linearity, impedance matching using lumped components, microstrip matching networks, low noise amplifier (LNA) design, active and passive mixers design, Wilkinson power dividers, directional couplers, hybrids, automatic gain control (AGC), cross-coupled oscillator, voltage controlled oscillators, power amplifier design.

Mode of delivery
