Active Power Divider (APD), featuring internal signal amplification, effectively compensates for line losses, enhances system signal-to-noise ratio, and extends transmission distance, offering a significant advantage in distributing weak signals. This APD is versatile, suitable for systems such as two-way radios, satellite positioning systems, 2.4GHz, and 4G LTE, with benefits including wideband, high isolation, low noise, and stable performance.
