AM transmitter PCB
This PCB changes amplitude to transmit the signal at 540-1700 kHz frequency deviation. There are low-level and high-level AM transmitter PCBs based on the level of modulation.
Wireless transmitter PCB
Digital signal processing (DSP) is applied in this case.
Wireless Transmitter PCB
SSB transmitter PCB
It transmits just one sideband of signal to the radio waves. It consists of a conductive PCB layer and a substrate layer. It is especially for the non-professional signal transmission system.
This cost-effective PCB transmits digital signals. Here, digital data are applied to the DSP mechanism at first. Then the signals go to the low pass filter via a digital to analog converter.
Next, signals have to go through a 90⁰ phase shift by using a local oscillator. These signals are mixed and amplified before transmission.
Except for these, you can find UHF (Ultra High Frequency), VHF, superheterodyne. All of these types provide tremendous performance in the communication systems.

It amplifies an audio signal through the amplifier. Then it passes the signal to the oscillator circuit by using a coupling capacitor. This capacitor transfers the output signal to the power amplifier.
In this stage, the signal is amplified to get better broadcasting. In the end, an antenna is applied to send out the amplified signals. This PCB controls the entire process with great efficiency to ensure the optimum performance of communication devices.
What is The FM Transmitter PCB?
FM means frequency modulation. FM transmitter PCB is a low-power circuit that changes the frequency of the signal wave to send data. This is worthwhile in noise reduction and developing the quality of signal propagation.
FM transmitter PCB is the most effective part of high-frequency communication devices. It enables the device to transmit the signal frequency which is received by the FM signal receiver to make amplification.
FM Transmitter PCB
The frequency range of it is 88-108 MHz. This produces a maximum of 75 kHz of frequency variation in PCB-driven devices.
It can handle high voltage due to its “Q factor”. This Q factor refers to the quotient of the center frequency of the resonator and the bandwidth. This property enables it to regulate long-distance signal transmission technology.
Easy circuit operation and high saturation ability also enhance the compatibility of this PCB to a large extent. You can apply this to two-way mobile applications, FM radio, naval communication circuits, etc.

Now, you just need to fabricate a PCB board, place the circuit components properly, and tune the FM transmitter by following the manufacturer’s guide. This is the easiest way of a simple FM transmitter PCB assembly. Watch this visual representation on this PCB design:
What Is The Difference Between AM And FM Transmitter PCB?
AM (Amplitude Modulation) and FM (Frequency Modulation) transmitter PCB have differences concerning their signal modulation system. Here, a comparative analysis between these two is explained for you.
AM transmitter modulates the amplitude of the transmitted signal. Here, signal frequency and phase are not changed. But, the FM transmitter varies the frequency of transmitted waves without changing the amplitude and phase.
This PCB deals with 88-108 MHz frequency at 1200-2400 bps (bit per second) rate. On the contrary, AM transmitter’s frequency range is 535-1705 kHz. Here, the data transmission rate is 1200bps.
FM transmission PCB provides wider bandwidth than AM transmission. In the AM transmission, bandwidth should be two times the maximum frequency of modulation. But, the bandwidth in FM transmission is double the sum of frequency variation and modulating frequency.
It delivers more effectiveness to reduce the signal noise than AM transmission system.
AM Transmitter PCB
This PCB renders higher durability and better quality of the signal at a competitive rate. But, AM transmitters are cheaper compared to FM. But it suffers from high noise signals.

How To Reduce The EMI Effect In A Transmitter PCB?
A transmitter PCB suffers from different EMI (Electromagnetic Interference) effects. These effects hamper signal transmission in many ways. That’s why you have to be aware of the EMI reduction techniques of the PCB.
- Sometimes, there is an excessive flow of energy via the conductors that produce conductive EMI. A well-placement of PCB components and regulated voltage supply reduce this type of EMI.
- Bypass capacitors create capacitive EMI in the power supply line. You have to place these capacitors far from the IC to avoid the capacitive EMI effect.
- When a bad signal is transmitted, it creates radiative EMI. You can apply the cable shielding method to resist the transmission of undesired signals.
- Proper use of component shielding can reduce inductive EMI effects. This EMI occurs in the connected lines or PCB ground planes. Component shielding controls the antenna size to absorb such EMI.
Transmitter PCB EMI Reduction
Which EMI Shielding Process Is Useful To Transmitter PCB?
To resist EMI in a transmitter PCB, there are some effective ways to apply. The two most useful EMI shielding processes are explained here.
Cable Shielding Method
In data transmission technology, cables are the most common source of EMI. That’s why cable shielding absorbs the effect of EMI to a large extent. Again, this type of protection is useful to reduce parasitic capacitance, inductance, and resistance.
The cable shielding process is also reliable to resist EMI in high-frequency PCB applications.
Component Shielding Method
This is the most applied EMI shielding process in transmitter PCB. Component shielding provides great resistance against the penetration of EMI in transmitter PCB components.
Transmitter PCB EMI Shielding
This cable assembly shielding separates the EMI-producing component from the electric circuits. Then it makes a connection to the ground and minimizes the loop of the antenna. Thus component shielding reduces the EMI effect.
In most cases, shields are made of metal. “Faraday cage”, is a good example of component shields. It is designed with metal or foam to protect the PCB components from radiative EMI.
What Are The Limitations Of A Transmitter PCB?
Transmitter PCB has a lot of varieties. Each type provides immense benefits along with some limitations as well. Here, the notable limitations of a transmitter PCB are given.
- It is EMI-sensitive. So, you need to apply protective care to resist the EMI effect.
- Its cost is comparatively high.
- The circuit design of a transmitter PCB is more complicated compared to other PCB solutions.
Flawless Transmitter PCB
We deliver the most reliable transmitter PCB of different categories. Contact us to experience excellent communication through PCB-driven devices.
How Do You Test A Transmitter PCB?
A transmitter PCB requires regular inspection to maintain its high efficiency. We are here with some reliable performance testing methods of transmitter PCB.
Automated Optical Inspection
This is an image-dependent automated test of transmitter PCB. Here, the AOI machine captures some images of the PCB from different angles. A high-quality camera is integrated with this machine.
The inspector compares these images with the most perfect transmitter PCB. This is conducted automatically through the AOI machine. That’s why it is a fast but costly testing procedure. But, Its outcome is beyond question.
Electrical testing checks the functionality of a transmitter PCB at a specific current supply. The inspector checks the connections, solder joints, component placement, current rating, voltage drops, etc at a certain temperature and pressure.
Transmitter PCB testing
So, it takes a huge time. But this test can provide a trustworthy result at a low cost. You can also apply flying probe tests, visual tests, etc to check the performance of a transmitter PCB.
