Problem 5: Cutoff and waveguide wavelengths. Design a microwave filter operating at the frequency of 10GHz,...
An attenuator can be made using a section of waveguide operating below cutoff. Such a device consists of a waveguide of width a, followed by second section of the waveguide of width a/2 and finally with another section of width a If a 2.286 cm and the operating frequency is 12 GHz, determine the required length of the below-cutoff section of waveguide to achieve an attenuation of 100 dB between the input and output guides.

Design a low pass filter with a cutoff frequency of 1 kHz +/- 100 Hz and a gain of 16.0 dB +/- 1.0 dB in the passband. The R2 and C components of the filter control the cutoff frequency, and are inversely proportional to the cutoff frequency. So decreasing the resistance or capacitance will increase the cutoff frequency. The R1 and Rf components determine the gain of the amplifier. Increasing the value of Rf will increase the gain. Increasing the...
