Product Code : SCL-EELE-12158
Indian Lab Suppliers supplies the Two Stage R-C Coupled Transistor Amplifier with power supply (Product ID: 12158) as part of its electronics engineering lab equipment range. It is a training board for studying two R-C coupled transistor amplifier stages, singly and in cascade.
Quick Answer
Two PNP transistor stages are powered by an IC-regulated −12 V DC supply on the board. Students draw the overload characteristics, plot the frequency response of each stage and of the cascade, and calculate the input and output impedance of each stage and of the complete amplifier. Cascading raises the gain (roughly the product of the stage gains, less loading) but narrows the bandwidth. The supply current, weight and size are not stated; please confirm at quotation.
