LX5561中文资料2.4GHz LNA, 3.3V, 2x2x0.5mm数据手册Microchip规格书

描述 Description

The LX5561 is a low noise amplifier (LNA) for WLAN applications in the 2.4-2.5 GHz frequency range. The LNA is implemented with bias circuit and input/output matching circuit on chip, resulting in simple external circuit on board. In addition, the onchip bias circuit provides stable performance of gain, NF and current for voltage variation compared to a general resistor-network bias circuit.
