RF Receivers are used to detect and respond to radio waves in devices for communication and other remote sensing applications. The CC113LRTKR is an integrated RF receiver and transceiver designed for wireless applications from Texas Instruments. It features a low power consumption and small package size, making it easy to use in low-cost designs. The following sections will discuss the CC113LRTKR application field and working principle.

CC113LRTKR Application Field

The CC113LRTKR is a sub-GHz RF transceiver that can be used for short-range wireless applications. It supports a wide range of frequency bands from 315 MHz to 915 MHz, depending on the specific product. Its small size and low power consumption make it ideal for embedded applications such as smart home automation, wireless lighting control, wireless metering, and home security systems. It can also be used in industrial and commercial applications such as radio frequency identification (RFID), asset monitoring, and access control.

The CC113LRTKR has several useful features that make it suitable for a wide variety of applications. It has an integrated near-field communication (NFC) protocol stack that supports ISO/IEC 15693 and FeliCa. It also has an integrated 4-kHz to 64-kHz low-power wake on radio (LWDR) mode that allows it to be woken up remotely and efficiently. Additionally, it supports a wide range of modulation schemes, including frequency-shift keying (FSK), 2-level FSK, Gaussian frequency-shift keying (GFSK), and 4RFK coding, making it highly versatile. Finally, it has a digital automatic frequency control (AFC) that enables it to constantly adjust its frequency to compensate for drifting due to temperature and other environmental changes, ensuring reliable performance.

CC113LRTKR Working Principle

The CC113LRTKR utilizes a direct-conversion transceiver architecture for efficient, low-power communication. In direct-conversion receivers, all signals are converted to baseband signals prior to being processed. The signal is received at the antenna, amplified, and filtered before passing through a front-end mixer. During this stage, the signal is mixed with the local oscillator signal, which converts it to baseband. The baseband signal is then delivered to the baseband block, where it is digitally processed to recover the transmitted data.

The CC113LRTKR also features a receive filter to ensure that the signal is as robust as possible and an integrated voltage-controlled oscillator (VCO) for precise tuning. In addition, it has an internal Automatic Gain Control (AGC) that increases the receiver sensitivity when needed. The CC113LRTKR also supports multiple modulation types, including 2-level FSK, 4-level FSK, GFSK, and 4RFK coding, allowing for a variety of data rates. Finally, the CC113LRTKR has an integrated near-field communication (NFC) protocol stack that supports ISO/IEC 15693 and FeliCa.

Conclusion

The CC113LRTKR is an integrated RF receiver and transceiver designed for short-range wireless applications. It has a low power consumption, small package size, wide range of frequency bands, and a range of digital features, making it a versatile and cost-effective solution for applications such as smart home automation, wireless lighting control, wireless metering, and home security systems. Additionally, it supports a wide range of modulation schemes, including frequency-shift keying (FSK), 2-level FSK, Gaussian frequency-shift keying (GFSK), and 4RFK coding. Finally, its direct-conversion transceiver architecture and integrated voltage-controlled oscillator (VCO) provide efficient, low-power communication for reliable data transmission.
