How Does It Compare with Other JLab RC Coupled Amplifier Trainers?
| Model | Studies | Built-in parts | Instruments |
|---|---|---|---|
| This board (EL-AET-1456) | Overload characteristics; frequency response of each stage and the cascade; input and output impedance of each stage and the cascade | −12 V IC-regulated supply; two PNP transistors | External decade audio frequency generator, AC millivoltmeter and decade resistance box |
| R.C. Coupled Amplifier Two Stage | Voltage gain and frequency response | Two transistors on the front panel; one DC regulated supply | Function generator, VTVM and oscilloscope as optional extras |

Choose this board when the practical goes beyond gain and bandwidth to the overload behaviour and the input and output impedance of each stage and of the cascade. The R.C. Coupled Amplifier Two Stage covers voltage gain and frequency response, and the RC Coupled with Inbuilt Two AC Millivoltmeter reads input and output on its own meters.
What Is the Two Stage RC Coupled Amplifier Used For?
In an RC coupled amplifier a coupling capacitor passes the signal from one stage to the next while blocking the DC, so each transistor keeps its own bias. Cascading two stages multiplies the gain, but the input impedance of the second stage loads the first, which is why the board measures the impedances of each stage as well as of the cascade. The frequency response shows the flat mid-band region and the fall at low and high frequencies, and the overload characteristic shows the input level at which the output starts to distort. The experiment is part of analog electronics courses in diploma, BSc electronics and engineering labs.
Frequently Asked Questions
Why is the cascade gain lower than the product of the two stage gains measured separately?
Because the second stage’s input impedance acts as an extra load on the first stage, lowering its gain once the two are connected. Measuring the input and output impedances of each stage shows the size of this loading effect.
Why does the gain fall at low and high frequencies?
At low frequencies the reactance of the coupling capacitors rises and cuts the signal; at high frequencies the transistor’s internal capacitances and stray wiring capacitance shunt it. Between the two lies the mid-band, where the gain is nearly constant.
What other apparatus is needed?
A decade audio frequency generator, an AC millivoltmeter and a decade resistance box. JLab’s audio signal generator, AC millivoltmeter and decade resistance box are separate items, linked below, that can be quoted on the same enquiry.
What information is needed for an export quotation?
The number of boards, the destination country and port or city, delivery terms such as FOB or CIF, and any packing, labelling or tender requirements.
Who manufactures the Two Stage RC Coupled Transistor Amplifier?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of analog electronics trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The board is produced at JLab’s own works and not bought in from a trader, so colleges, institutes, dealers and importers buy it from the maker, each board is visually inspected before dispatch, and repeat orders are handled by the same works. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. It exports worldwide and ships to buyers in every region — for example Gabon in Central Africa, North Macedonia in Southern Europe, Honduras in Central America and the Caribbean, Norway in Northern Europe and Canada in North America. Tender details are on the JLab lab tenders page.
