ZKxx-UM series is Zeenko's USB interface powered RF low noise amplifier with convenient power supply interface, moderate gain, high IP3 and low noise. The ZKxx-UM series is powered by USB type-C interface, and the built-in high PSRR LDO can effectively reduce the power noise, which effectively reduces the noise floor compared with other vendor's USB direct-feed modules.
The ZKxx-BM series is a USB-powered RF low noise amplifier with built-in battery introduced by Zeenko. Based on the ZKxx-UM, it adds a battery and reduces power consumption, making it suitable for portable use. Compared with modules from other vendors with built-in batteries, it has a flatter and more consistent gain, lower noise figure, smaller size, and longer battery life.
