4/2/2009 The Quarter Wave Transformer.doc 4/7 Jim Stiles The Univ. of Kansas Dept. of EECS Problem #1 The matching bandwidth is narrow! In other words, we obtain a perfect match at precisely the frequency where the length of the matching transmission line is a quarter-wavelength. Æ But remember, this length can be a quarter-wavelength atQuarter Wave Transformer Impedance Calculator. A quarter wave transformer is used to match two transmission lines with different impedances. As the name suggests, the length of this transmission line if fixed at a quarter of the wavelength (λ/4). This is a required field. This is a required field.(a) Without a transformer (b) With a transformer Example 19. Determine the SWR, characteristic impedance of a quarter wavelength transformer, and the distance the transformer must be placed from the load to match a 75 Ω transmission line to a load ZL = 25 - j50 EXERCISE (Submit after 15 mins.)

First, a regular quarter-wavelength transformer can be designed for the lower band, e.g. according to [3]. Operation in the upper band can then be achieved by utilizing its harmonic performance at three quarter-wavelengths. Such an example is shown in Fig. 2 (dashed line) for a dual-C-band transformer from a square to regular C-band cross section.The basic impedance transformer is the quarter-wavelength transmission line. Its impedance transforming ratio is not high and the bandwidth is narrow and uncontrollable. To solve these problems, the impedance transformer with a filtering function begins developing, besides the multi-section cascade method.The quarter-wavelength approach is a technique that is used to match the transmission line to the antenna using a transformer. The impedance characteristics of the transmission line are restricted in terms of the range and values; thus, the quarter-wavelength transformer technique is most suitable when microstrip transmission lines are used ... ….

The Shortened Quarter-Wavelength Transformer Another less well-known but useful adaptation of the quarter-wavelength transformer is the shortened, double-section transformer depicted in Figure 10. I will refer to this as type 13. Like the standard transformer, it is used to match real impedances. But the required length isA quarter-wave impedance transformer is a useful and simple matching network that is used to match the impedance of a terminating load (Z L) to the characteristic impedance of a feeding transmission-line (Z 0) . It consists of a quarter-wavelength transmission-line, whose input impedance can be easily calculated using the expressionSome studies investigate the electromagnetic transients in half wavelength transmission lines [8, 9]. However, much less can be found about quarter wavelength power lines and cables. The authors in [2] give the quarter resonance as an example when studying the classic case of transformer energization via a cable without detailing the …
