FM Wireless Remote Control Module, FM Radio Transmitter Module, Walkie-Talkie Amplifier Module. The low-frequency end input of 1 mW can deliver a maximum output power of 2.0 W; maximum output is 1.6 W at 512 MHz, 1.0 W at 930 MHz, and 1.0 W at 1000 MHz. The amplifier features an integrated heat sink for stable long-term operation. Before powering the module, connect the RF input (RFin) and RF output (RFout) terminals first, then connect the DC power supply. When applying DC power, ensure correct polarity—reversing the connections may damage the module. Operating Frequency Range: 1–1000 MHz Gain: 35 dB (decreases with increasing frequency) Input Power: 1 mW (0 dBm) Maximum Output Power: - 2.5 W (34 dBm) at 10 MHz - 2.0 W (33 dBm) at low-frequency end - 1.25 W (31 dBm) at 512 MHz - 1.0 W (30 dBm) at 1000 MHz Operating Voltage: 12–15 V DC Note: At 15 V input, the module can deliver up to 2.5 W output, but extended operation at maximum power may cause overheating. The module includes thermal protection and will automatically shut down if the heatsink becomes excessively hot. Operating Current: 300–400 mA (varies with output power) RF Connector: Standard SMA female Color: Black and Silver Material: Plastic Note: Label appearance may vary slightly between batches; this does not affect functionality. Package Includes: 1 × RF Power Amplifier Module Note: Color representation in images may vary slightly due to lighting and screen settings. Dimensions are subject to a tolerance of ±1–3 cm.
