IF Amplifier

By Kelvin Leung, Norman Bo, and David Ritter

This application describe the usage of a Motorola MC1350 Monolithic IF Amplifier.

A modern wireless communication system consists of a transmitter and a receiver. The transmitter outputs an electromagnetic signal at a certain frequency into the air. The receiver receives that particular signal and demodulates it into the original signal. As the electromagnetic wave get transmitter into the air the amplitude of the signal will decrease. In order for the receiver to demodulate the received signal, the signal has to be amplified before it is fed into the demodulator in the receiver. This is where the MC1350 Monolithic IF Amplifier will come into place.

This MC1350 Monolithic IF Amplifier is manufactured by Motorola. The datasheet of the IC can be found here. This amplifier is designed with AGC range from 60 dB minimum, at frequency from DC to 45MHz, ideal for radio and TV signal amplification.

A detail description of the usage of this amplifier will be provided at a later date.
