    A transmission line is a two conductor system, usually with uniform cross-section, used to guide electromagnetic energy between two places. At low frequencies (and to a good approximation for many microwave guiding structures) the energy is transferred via the voltages developed between the conductors, and the currents flowing through the conductors. A coaxial line and a two-wire line are examples... View full abstract»

  • Smith Chart

    We have shown that reflection coefficient can be used to solve the impedance transformation problem along a transmission line, provided the normalised impedance/reflection coefficient equation can be easily solved. We have shown that the reflection coefficient can be plotted, and transformed, on an Argand Diagram. The Smith Chart is the superposition of normalised impedance contours for positive r...

  • Microstrip circuits

    Wires used to interconnect components will have both a distributed series inductance and shunt capacitance per unit length. When the length of the wires becomes greater than about one-tenth of a wavelength, then the transmission line effects associated with the distributed series inductance and shunt capacitance can no longer be ignored in circuit design. In order to take these effects into accoun... View full abstract»

    Switches are widely used in many RF systems, from low power transmit-receive switches in time division duplex wireless transceivers to millimetric wave beam-squinting systems for satellite tracking to high power (often military) phased array systems. This paper examines the operation of the PIN diode as a switching element and presents a number of design techniques for a variety of applications. C... View full abstract»

  • Filters [amplitude response]

    Publication Year: 2000, Page(s):5/1 - 516
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (700 KB)

    In some applications the phase response of a filter is of no consequence and the filter need only be designed to exhibit a specific amplitude response, but in other applications, for example satellite communication, the phase response is important and the filter must be designed to exhibit both a specific amplitude and phase response. An alternative approach is to design the filter to have a speci... View full abstract»

  • RF amplifier design

    Publication Year: 2000, Page(s):6/1 - 6/8
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (496 KB)

    The paper begins with a summary of core theory and equations that are applicable to RF amplifier design. It will review considerations for both discrete and RFIC implementation and especially consider low noise RF amplifiers as these tend to require the greatest amount of amplifier design effort in any wireless transceiver. Finally an example is covered that deals with the design of a 900 MHz cell... View full abstract»

    Readily available harmonic balance simulators can be used to accurately predict the frequency, output power and harmonic content of RF and microwave oscillators. Phase noise can also be simulated, although values are highly dependent on the flicker noise parameters within the non-linear model. In the absence of a non-linear simulator, a relatively cheap small-signal simulator can still be used to ... View full abstract»

  • How to design RF circuits-synthesisers

    Publication Year: 2000, Page(s):8/1 - 811
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (760 KB)

    Frequency synthesisers form the basis of most radio system designs and their performance is often key to the overall operation. This paper will present an introductory overview of the basic parameters governing the design of a phase locked loop frequency synthesiser and their effects, with the sources of phase noise within a design also being considered. Finally a list of common problems, along wi... View full abstract»

    Mixers are frequency translation devices. They allow the conversion of signals between a high frequency (the RF frequency) and a lower Intermediate Frequency (IF) or baseband. In communications systems the RF is the transmission frequency, which is converted to an IF to allow improved selectivity (filtering) and an easier implementation of low noise and high gain amplification.

  • The basics of radio system design

    Publication Year: 2000, Page(s):10/1 - 10/7
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (534 KB)

    This paper is intended to give an overview of the design of radio transceivers to the engineer new to the field. It is shown how the requirements of a radio are derived from link budget calculations and then the modulation scheme, transmitter and receiver cascades are designed to fulfil them.

    The electrical characteristics of the printed circuit board (PCB) used to physically mount and connect the circuit components in a high frequency product will have a significant impact on the performance of that product. The potential magnitude of the effect of the PCB design increases with frequency as the parasitic elements tend to a similar magnitude to the typical lumped components used. This ...
