Increase Signal Capabilities with Amplifier PCBs of PCBTok

Amplifier PCBs are an integral part of any electronics project. Whether you are building a power amplifier, audio amplifier or oscillator, we have the right product for your needs. These devices can be used in different applications like audio amplifiers, RF amplifiers and radio frequency circuits. They are available in different configurations such as single stage and multi-stage devices.

If you’re looking for a way to increase the signal capabilities of your circuits, you might want to consider using Amplifier PCBs from PCBTok. These boards are specially designed with the intent of amplifying signals, which can be useful for many applications. The board itself is made from FR-4 material, which means that it’s strong and durable enough to withstand daily use.

As your company grows, so does the need for a reliable signal. The first step to achieving this is by using PCBTok’s amplifier PCBs. These are small PCBs that can be used in a variety of ways to boost the signal in your system. They can be used as an active component or as a passive component, depending on how you want to implement them.

Amplifier PCB By Type

Voltage Amplifiers

Voltage amplifiers are the simplest in design and have the lowest internal noise of any type amplifier. They are characterized by low output resistance, high input impedance and high open-loop gain.

Current Amplifiers

Current amplifier is a basic, but very useful and common circuit. It takes in a small current (usually DC), and outputs another much larger current. The output signal always has the same polarity as the input signal.

Power Amplifiers

Power amplifiers are used to amplify a signal. They convert a low-power signal to a higher power one. An audio amplifier turns the weak signals coming from your stereo speakers into a louder, more powerful audio signal.

Audio Frequency Amplifiers

The intermediate frequency amplifier is a class of amplifiers that are used in superheterodyne radios, in which the incoming signal is mixed with a local oscillator to produce sum and difference frequencies.

Radio Frequency Amplifiers

Enables the input signal of broadcast or transmitted information to control an output signal. The amplifier uses frequency-determining networks to convert the input signal into an output signal.

Ultrasonic Amplifiers

Ultrasonic amplifier is a high-frequency signal amplifier specifically designed to handle ultrasonic frequencies. Most often used in piezo transducer and sensor applications, up to tens of megahertz.

Amplifier PCB By Classification (6)

  • Class A Amplifier

    The Class A amplifier is a basic, single-stage design. It utilizes a single switching transistor in the standard common emitter circuit configuration to create an inverted output.

  • Class B Amplifier

    Class B amplifiers also conduct during both halves of the input cycle; however they conduct with opposite polarity. The result is reduced switching loss and increased efficiency.

  • Class AB Amplifier

    Class A/B amplifiers combine the reliability and robustness of class A operation with the efficiency of class B operation to achieve even higher power efficiency.

  • Class C Amplifier

    One of the most efficient classes of power amplifier is a class C amplifier. A transistor conducts less than 180°, but this reduces distortion at the expense of efficiency.

  • Class D Amplifier

    Class D amplifier is an output switching waveform, higher than the highest audio signal that needs to be reproduced for it is this high frequency switching.

  • Class GH Amplifiers

    Switch to a higher voltage when the audio signal wave has a peak value that is a higher voltage than the level of the supply voltage, reducing heat and increasing efficiency.

Amplifier PCB by Function (5)

  • DC Amplifiers

    Direct-coupled amplifiers are a type of amplifier that permits signals with zero frequency, also referred to as direct current, to pass from input to output. Constructed for low impedance inputs and outputs with active or passive preceding elements.

  • Buffer Amplifiers

    Buffer amplifiers are electrical devices that provide electrical impedance transformation from one circuit to another, with the aim of preventing the signal source from being affected by whatever currents that the load may be produced with.

  • Video Amplifier

    Video amplifiers are used in video cable extension, video recording systems and other applications where analog video signals must be amplified, buffered and filtered. Common applications include video cable extension, floppy disk head amplifiers.

  • Operational Amplifiers

    An operational amplifier is an electronic device that helps amplify small electrical voltages. It does this by taking a small input voltage, converting the voltage into an output voltage. Used in many circuits today for devices’ operational capability.

  • Transistor Amplifiers

    Transistor amplifiers are a common device in electronics. A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition.

Qualities and Characteristics of Amplifier PCB | PCBTok

Qualities and Characteristics of Amplifier PCB PCBTok
Qualities and Characteristics of Amplifier PCB PCBTok (1)

The quality and characteristics of an amplifier PCB are important factors to consider when choosing a PCB for your next project.

There are several qualities to look for in an amplifier PCB, including:

  • High input impedance. This is very important at the input signal as it helps the voltage drop entirely on the amplifier.
  • Limited bandwidth. A wide bandwidth means that more frequencies can be amplified by the circuit, but this can also mean that you have a lower frequency response and increased distortion.
  • High open-loop gain. This is how much gain your circuit will have before feedback kicks in and starts to reduce it.
  • Low output impedance. The lower the output impedance, the less distortion there will be in your sound wave after amplification.

Amplifier PCB Fabrication

Amplifier PCB’s Classification

An amplifier is a device that increases the power of an output signal. It is used in many electronic devices, such as radios and televisions, as well as industrial machines. An amplifier can also be used to boost an audio signal for a sound system.

There are several different types of amplifiers, each with its own characteristics and uses. The most common types are Class A, A/B, B and C amplifiers. In addition, there are other types of amplifiers that have been developed specifically for certain applications. All available here at PCBTok!

Amplifier PCB’s High Input Impedance

The input impedance of a circuit is defined as the ratio of voltage to current at the input terminals.

Amplifier PCBs with high input impedance provide more damping for transients, which means they can handle more sudden changes in signal and are less susceptible to noise.

Amplifier PCB’s high input impedance is the ability to isolate a signal from its source. This is important in many cases, especially when the amplifier is receiving signals from a wide range of different sources.

OEM & ODM Amplifier PCB Applications


Amplifier PCB’s used in Television incorporate many features, including high performance, economic operation and product reliability. Our amplifiers are designed to deliver consistently high quality results.


There are many types of amplifier that can be used in radio. Amplifiers can be used as radio amplifiers which increase the power level of a signal, or as radio frequency amplifiers that amplify the frequency range of a signal.


Amplifier PCB’s used in oscilloscopes are one of the most important parts of an oscilloscope. The amplifiers are the medium through which a signal is converted into voltage or current form so that it can be displayed on the screen.

Music Instruments

PCB’s used in music instruments need to carry a high current load, while the signal they carry through the circuit needs to be very low. This circuit uses an optoisolator as input and output device, protecting the signals from noise.


Amplifier PCBs used in microwave will be designed and developed by our experts. We are a leading supplier of microwave PCBs with an experienced team of engineers who design, manufacture and test all components using state-of-the-art technology.
