This module uses a large number of filter capacitors as power decoupling function, large area paving and drilling, according to high-frequency circuit design, has good frequency characteristics. The power supply uses RT9193 chip, and the sheet metal is used for gold deposit processing. [name]: pe4302 RF Attenuator Module [Size]: 50mm x 50mm [Power supply voltage range]:5V [The maximum input power ]: +24dBm Module usage instructions: LE is on the opposite side of ON, P/S is on the opposite side of ON, the module is programmed mode; LE is on the opposite side of N, P/S is on the opposite side of N, the module is dial control mode, at this time, the attenuation is controlled by six dial codes from CO.5 to C16, and the attenuation is the sum of dial codes. For example, when 20dB attenuation is required, C16 and C4 can be dialed to ON terminal. Color: As Shown Material: PC Package Contents: 1 * PE4302 Module
