Working Principle
The SKY14151-350LF-EVB includes a range of transceiver components which allow it to fulfill its functions. The integrated components on the board include the Low Noise Amplifier (LNA), an RF Deck, power amplifier, power down switch, power switch, balun, a circulator, and PLL. Signals sent from the output port of the RF deck go through the LNA. After passing the filter and the PLL block, the signals then reach the power amplifier and get sent out to the antenna. Input signals coming from the antenna enter the circulator, which helps amplify and isolate the signal, thus making it immune to any external noise and other interference. The signal is then filtered and sent to the power switch block, which eliminates amplitudes which are too low to process. After that the signal then enters the PLL block where the data is decoded and then sent to the receiver port of the RF deck.
Conclusion
The SKY14151-350LF-EVB is an RF Evaluation kit board designed to make the development of wireless applications a simple and cost effective exercise. The kit can be used in a wide variety of applications in both commercial and consumer applications. The integrated circulator component on the board helps reduce noise and interference, thus increasing the range of applications for which it can be used. The working principle of the board is simple - data is received through one port, processed and then outputted on the other.
