1. All modules in this store must first be connected to the input end (RFIN) and the output end (RFOUT) and then supplied with power (DC) (connect the DC power supply). 2. If the module is powered by DC power, that the positive and negative DC poles are connected correctly. Do not reverse the connection! Otherwise, the module be damaged! 863MHz-873MHz Ultra-Low Noise Amplifier Module Note: Connect the input signal and output load before use. Bandwidth: 863MHz-873MHz Power supply: 3V-5V/55mA : Less than 0.6dB (typical value) Maximum input power: 0dBm Maximum output power: 100mW (20dBm) Gain: As shown in the list below Input and output impedance: 50 Input voltage Vpp: Less than 0.225V Housing: CNC precision machining Connector type: SMA female (external thread, inner hole) Size: 33mm x 21mm x 10.5mm (without connector) Instructions for use: RFin is the signal input Connection RFout is the signal output connection. GND is the negative terminal of the DC power supply. DC is the positive terminal of the DC power supply.
