Amplitude Modulation (AM) Modulator Circuit using 741 IC

Electronic Kit School. - In propagation of signal we knw there three kinds of mmodulation there are amplitude modulation, frequency modulation, and pulse modulation. One of the modulation mentioned is amplitude modulation or AM that the amplitude of signal be modulated and change in ever time. 

There are electronic design circuit to build AM modulator simply and also complex to give est result for user. One of the AM modulator circuit is look like in Figure 1 below with the main component used is 741 IC that also called with Op-Amp integrated circuit that also popular today.

The main component to modulated the AM in this circuit one again is 741 IC which popular today. In this time, beside we will show you the circuit, here we also will show you component part and global description about this circuit.

Circuit 

  1. 741 IC
  2. Resistors
  3. Capacitors
  4. Variable Resistors
Description

Circuit like in Figure 1 above show you about the AM modulator using the main component 741 IC. From Engineersgarage site describe that the AM demodulation is done using a low pass filter which can filter out the high frequency carrier from the AM wave in such a way that only the envelope of the carrier wave appears at the output of the filter. The amplitude of the filtered wave has variations corresponding to the amplitude of the modulating low frequency signal.

To get a better filtering using the Low pass filter the carrier frequency must be as large as possible and hence the carrier frequency generator circuit explained in the article AM modulation has to be modified for a very high frequency carrier signal. The only change that is required is the value of the capacitors C1 and C2 which determines the carrier frequency generation.

The value of R1 is kept the same as 1K but the value of the resistance R2 can be varied. As the value of the R2 decreases the output frequency of the circuit increases. As it is mentioned in the article AM modulation that the minimum value of the R2 which produces the highest stable frequency is around 130 ohms. In this project to increase the carrier frequency at least 10 times that achieved in the previous project the value of C1 and C2 is reduced to 10 times than that used in the previous AM modulation project.

High-band DPD Demodulator Circuit with Integrated DSA and RF Switch

Electronic Kit School. - There are many electronic circuit design to give best result now for demodulator. One electronic circuit of High-band DPD Demodulator with Integrated DSA and RF Switch which designed is look like in Figure 1 below.

The main component to controller this motor is IDTF1370 which popular today. In this time, beside we will show you the circuit, here we also will show you component part and global description about this circuit.

Circuit 

  1. IDTF1370 IC
  2. Resistors
  3. Capacitor
  4. Inductor
  5. Jack
Description

Circuit like in Figure 1 above show you about the High-band DPD Demodulator Circuit with Integrated DSA and RF Switch. From Electroschematics site describe that the device has an RF input, standby mode and attenuator setting may be set using the F1370 serial port input. It has a built-in digital step attenuator (DSA) and single-pole-double-throw switches (SP2Ts). The signal coming out of the power amplifier is receive so that the I&Q (In-phase and Quadrature) data at the Baseband can be pre-distorted before being sent to the transmitter’s digital-to-analog converter to counteract the distortion inherent in the downstream PA. The signal coupled from the PA is adjusted via a DSA to a lower level and then sub-sampled at an IF frequency of ~200 MHz which necessitates the need for a highly linear demodulator to downmix to quadrature IF from the Transmit frequency. Sampling IF_I and IF_Q independently and then digitally combining these signals can achieve an effective doubling of the sample rate. Any distortion in this path will degrade the performance of the DPD algorithm. By utilizing an ultra-linear demodulator with integrated DSA such as the IDT F1370, the ACLR and/or power consumption of the full Transmitter system can be improved significantly.
