Analyze a balanced mixer using a 180? hybrid junction. Find the output IF current, and the input reflections at the RF and LO ports. Show that this mixer suppresses even harmonics of the LO. Assume that the RF signal is applied to the sum port of the hybrid, and that the LO signal is applied to the difference port.
An inverting amplifier With nominal gain of -20V/V employs an op amp having a dc gain of 10^4 and a unity-gain frequency of 10^6 Hz. What is the 3-dB frequency f3dB of the closed-loop amplifier
A certain amplifier has an input voltage of 100 mV rms, an input resistance of 100kΩ, and produces an output of 10Vrms across an 8-Ω load resistance. The power supply has a voltage of 15 V and delivers an average current of 2 A. Find the power dis..
Our third word problem case study described a logical "function unit" that computed the eight combinational functions of the inputs A and B: constant 1, A OR B, A NAND B, A XOR B, A XNOR B, A AND B, A NOR B, and constant 0.
Calculate the ratio horizon for a 500-ft transmitting antenna and a receiving antenna of 20 ft. Calculate the required height increase for the receiving antenna if a 10% increase in the radio horizon were required.
