BLF871S,112 Typical application Circuitry

BLF871S,112

The BLF871S,112 is a high-power, LDMOS transistor designed for broadcast transmission applications, such as television and radio broadcasting. It operates in the VHF (Very High Frequency) range, providing a robust solution for high-efficiency RF power amplification.

Application Scenarios

The BLF871S,112 is primarily used in VHF broadcasting transmitters and industrial, scientific, and medical (ISM) applications requiring high-power RF amplification. It's suitable for analog and digital broadcast television, FM radio broadcasting, and high-power industrial RF heating applications.

Parameter Features

- Frequency Range: Designed to operate efficiently in the VHF frequency band.

- High Power: Capable of delivering high RF output power, essential for broadcasting applications.

- High Efficiency: Engineered for high efficiency to reduce power consumption and heat dissipation.

- Robustness: Built to withstand high VSWR (Voltage Standing Wave Ratio) conditions, making it reliable in demanding environments.

Circuit Connection Example: VHF Broadcasting Transmitter

In a VHF broadcasting transmitter application, the BLF871S,112 can be used as the final RF power amplifier stage, amplifying the modulated RF signal to a power level suitable for transmission over a significant distance.

1.Power Supply and Biasing:

- VD (Drain Voltage): Connect the drain (through an appropriate matching network) to a power supply capable of delivering the required voltage and current. The exact voltage depends on the desired output power and efficiency.

- VG (Gate Bias Voltage): Apply a bias voltage to the gate to set the transistor in the desired operating class. A bias-tee might be used to inject the DC bias onto the RF signal path.

2.RF Input and Output:

- RF Input (Gate): The modulated RF signal is applied to the gate through a capacitive coupling or a suitable matching network to ensure impedance matching.

- RF Output (Drain): The amplified RF output is taken from the drain, again through an appropriate matching network or filter to ensure the signal is within the desired frequency band and to protect against harmonic emissions.

Design Considerations:

- Thermal Management: The BLF871S,112 can generate significant heat. Ensure adequate cooling, such as heat sinks or forced air cooling, to maintain operational stability.

- Matching Networks: Proper input and output matching is crucial for maximizing power transfer and efficiency. Use impedance matching networks to match the BLF871S,112 to the 50-ohm system impedance.

- Protection Circuits: Given the high power levels, incorporate protection circuits to safeguard against over-voltage, over-current, and excessive VSWR conditions.

- Harmonic Suppression: Design output filters to suppress harmonics and meet regulatory requirements for RF emissions.

By addressing these design considerations and effectively leveraging the BLF871S,112's capabilities, developers can create efficient and robust VHF broadcasting transmitters. This ensures reliable communication over vast distances, meeting the demands of modern broadcasting applications.
