Key Product Features: Powerful 1W Output: Provides stable power output of up to 30dBm (1W) in the core FM broadcast band (88-108MHz), meeting the needs of small transmitter systems. Wideband Operating Range: Supports a wide frequency range of 85-115MHz, covering the standard FM broadcast band with some margin, providing greater application flexibility. Low-Voltage, High-Efficiency Drive: Requires a single 4.5V-6V DC power supply, drawing approximately 0.5-0.6A, making it ideal for integration in portable, battery-powered, or low-voltage systems. High Signal Gain: Provides 32dB of small-signal gain, effectively boosting input signal strength and reducing requirements for preamplifier signal sources. Standard Impedance Interface: Both input and output features a 50 ohm characteristic impedance and come standard with a standard SMA female connector, ensuring plug-and-play compatibility with common equipment and cables. Class A Amplifier Quality: Utilizing a Class A amplifier design, it provides excellent signal linearity and low distortion, making it particularly suitable for FM broadcast applications where signal quality is crucial. Modular Design: Available in a bare-board format, it offers a compact design, allowing for flexible integration into chassis or systems based on project requirements.
