Exercise : Microwave Communication - Section 4
1.
The domain mode in rectangular waveguide is
2.
The reverse voltage applied to a varactor diode
Answer: Option
Explanation:
The action of varactor diode is due to the capacitance of depletion layer. The thickness of depletion layer depends on the reverse bias which should not cause breakdown.
3.
To ensure that only dominant mode TE10 is allowed to propagate in an air filled rectangular waveguide, the lower frequency limit and upper frequency limit are
4.
The skin depth at 1000 MHz as compared to that at 500 MHz is
5.
The transit time (in cycles) for electrons in repeller space of reflex klystron oscillator for sustaining oscillations is (n is any integer)
