• Low-power consumption
• Wide tuning range – 1.2 to 3.5 GHz
• High linearity
• High SNR
• Low noise figure

Application Fields

The SI2182-A50-GMR is ideal for consumer-grade radio receivers used in satellite, cable, broadcast, and terrestrial radio, as well as common portable and mobile electronic devices. It can be used in FM, AM, CB, DAB, DRM/Frequency Modulated continuous wave (FMCW), dual-sideband (DSB) and EDGE radios. The integrated low-noise amplifier, filter, mixer and demodulator make this a great choice for applications where precision and performance are paramount.

Working Principle

The SI2182-A50-GMR utilizes a mix of integrated circuits and components to process the incoming RF signal. An antenna is used to receive an RF signal. This signal is then routed to a low-noise amplifier to further amplify the signal. The signal is then routed to a filter that only allows the desired signal to pass through, while removing any unwanted signal. The filtered signal is then sent to a mixer, which is used to convert the desired signal into an intermediate frequency (IF) signal. The IF signal is then routed to a demodulator, which is used to remove the carrier wave and extract the data that is being transmitted.

Conclusion

The SI2182-A50-GMR is an integrated single-chip solution for consumer-grade radio receivers. It offers a wide range of features such as a low-noise amplifier, filter, mixer and demodulator, as well as low power consumption and wide tuning range. The SI2182-A50-GMR is suitable for use in portable and mobile devices and is ideal for applications where precision and performance are paramount, such as satellite, cable, broadcast, and terrestrial radio receivers. With its integrated low-noise amplifier, filter, mixer and demodulator, the SI2182-A50-GMR provides an effective solution for these applications.
