A 20 dBm power source is connected to the input of a directional coupler having a coupling factor of 20 dB, a directivity of 35 dB, and an insertion loss of 0.5 dB. If all ports are matched, find the output powers (in dBm) at the through, coupled, and isolated ports.
A wave traveling in a lossless, nonmagnetic medium has an electric field amplitude of 24.56 V/m and an average power density of 2.4 W/m2. Determine the phase velocity of the wave.
Using the devices above, please construct the 555circuit. use circuit-building software you want andmeasure and record the frequency and the duty cylcle of theoutput. Also, include the picture of the constructed circuit.
Calculate the carrier frequency and corresponding frequency bandwidth for a microwave communication system operating at 10 cm with a microwave bandwidth of 0.2 mm and for an optical communication system operating at 1.35 micrometers with an optical b..
When a 0.900kg mass oscillates on an ideal spring, the frequency is 1.49Hz . A)What will the frequency be if 0.300kg are added to the original mass. Try to solve this problem without finding the force constant of the spring.
The schematic shows a scheme for coupling and amplifying ahigh-frequency pulse signal. The circuit utilizes twon-channel MOFETs whose bias details are not shown and a 50 ohmcoaxial cable connecting the drain of Q1 to the source of Q2.
