Design an amplitude modulator using a variable gain amplifier, such as the HMC694LPE. The baseband signal is given by
x(t)=0.5cos(2Ïf 0 t)+0.5cos(4Ïf 0 t)V
The carrier frequency is generated using a dielectric resonator oscillator with an output power of 15dBm at a frequency of 10GHz. The modulated signal should have a mean power of 15dBm with a modulation depth of
+/â5 dB. Download the data sheets of the components from the manufacturer or distributor web sites to design your modulator circuit to meet the specifications. [f 0 =1MHz.]
