(A) The TW tube which is a wideband microwave amplifier of the helix is used as a slow wave structure of the device. (R) The phase velocity of the helix can be profiled along the length of the helix.
(A) The variables choosen for the equivalent circuit of a 2 port network in the microwave range of frequencies are travelling waves rather than total voltage and total currents. (R) In microwave range equipment is not readily available to measure total voltage and total currents at the ports of the networks. Short and open circuits are difficult to achieve over a broad-band of frequencies and active devices frequently will not have stability for a short or open circuit.
(A) In some applications, the TM01 mode in circular waveguide is preferred to the TE01 mode or TE11 mode. (R) TM01 mode not only overcomes the problem of rotation of polarisation in circular waveguide but also requires a smaller diameter.
(A) In an oscillation zone of reflex klystron an increase in the reflector voltage results in lighter oscillation frequency. (R) Electron bunches pass through the interaction gap before the retarding field is at a maximum and an increased reflector voltage results in the induced current lagging in voltage.
A 75 ohm transmission line is first short terminated and the minima locations are noted. When the short is replaced by a resistive load RL, the minima locations are not altered and the VSWR is measured to be 3. What is the value of RL?
A square waveguide carries TE11 mode whose axial magnetic field is given by: <table><tr><td rowspan="2">Hz = H0cos</td><td style="border-bottom:1px solid #000000;vertical-align:bottom;padding-bottom:2px;"><center> x</center></td><td rowspan="2">cos</td><td style="border-bottom:1px solid #000000;vertical-align:bottom;padding-bottom:2px;"><center> y</center></td><td rowspan="2">A/m</td></tr><tr><td style="text-align: center;"> 8</td><td style="text-align: center;"> 8</td></tr></table> Where the waveguide dimensions are in centimetres. What is the cut-off frequency of the mode?
