Zeenko low noise RF amplifier
Details
The Zeenko BM and UM series are RF low-noise amplifiers. The UM series provides a convenient power supply interface, moderate gain, a high IP3, and low noise. The UM is powered by a USB type-C interface, and the built-in high PSRR LDO can effectively reduce the power noise, which reduces the noise floor compared with other USB direct-feed modules.
The BM series is a USB-powered RF low-noise amplifier with a built-in battery. This model is based on the UM series and includes a battery and features reduced power consumption, making it suitable for portable use. Compared to other battery-powered amplifiers on the market, the BM series has a flatter and more consistent gain, lower noise figure, smaller size and a longer battery life.
