7W 88-108MHz MHz FM frequency power amplifier power amplifier 1mW with heat sink Note: The antenna must be connected (that is, use a coaxial cable to connect to the outdoors, the antenna GP or J-shaped. Never use a whip antenna directly connected to the output port, it not work properly, remember to remember), andThis antenna should resonate at the operating frequency, and the standing wave cannot exceed 1.5. Working frequency: 88-108MHz Output power: 7-8W Input power: 0.1-1mW (-10~0dBm, just one s9018 oscillator output power) Input and output impedance: 50 ohms Input and output terminals: SMA-k female Working voltage: 12V (15Vmax) Working current: 2A Output power and current consumption data from 65MHz to 110MHz: Color: As Shown Material: PCB Package Contents: 1 * Power Amplifier Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
