- | The circuit shown in the figure below is a high performance RF receiver system with 10dB of gain, optimized for operation at a center frequency of 5.8GHz. By keeping the input unfiltered and using a filter to attenuates out-of-band interferers at the amplifier output, the entire system noise figure performance is at 2dB. | + | |
- | The circuit includes a high speed overpower cutoff that protects sensitive downstream equipment connected to the receiver system. | + | |
- | The RF inputs and outputs are standard SMA connectors, and the entire design is powered from a single micro USB connector. | + | The circuit is a high performance RF receiver system with +23 dB of gain, optimized for operation at a center frequency of 5.8 GHz. The input is unfiltered, maintaining a noise figure of 2 dB, while a bandpass filter at the output attenuates out-of-band interferers. |
