RF Transceiver ICs are the vital elements of the wireless communication system, and they enable the integration of the various components in the RF path of the communication system. The frequency band of transmission is the main criterion in classifying RF transceiver ICs, which mostly operate at frequencies ranging from 300MHz to 6GHz. CC1200RHBT is the microwave transceiver IC that operates at 915MHz, a frequency band used for long-range communication applications and has a high data rate.

The CC1200RHBT is developed by Texas Instruments, a technology leader in the design and manufacture of semiconductors and integrated circuits, and is an integrated monolithic, which offers features like low current consumption, high efficiency, and wide bandwidth for long-range communication applications.

The various features of the CC1200RHBT allow users to reduce the overall cost and complexity of their wireless applications. It employs a baseband modulation and enables two-way transmission using the GAJT modulation technique, which is especially suitable for communication using low cost narrow-band RF transceivers. The features of the CC1200RHBT are:

• Low Power Consumption—Using a single 3.3V supply, the CC1200RHBT requires only 13 mA of RX and 19 mA of TX currents at 915MHz.
• High Efficiency—The CC1200RHBT achieves 95% direct conversion rate in TX mode and 84% in RX mode.
• High-bandwidth—The CC1200RHBT provides 76.8MHz of bandwidth with a maximum data rate of 300Kbps for reliable long-range communication applications.
• Integrated Power Amplifier—The power amplifier of the CC1200RHBT has been optimized for thermal performance and can provide up to 25 dBm of current.
• On-chip Antenna Switch—The antenna switch built into the chip significantly reduces the cost of external components, which must be purchased separately in other RF transceiver ICs.

The CC1200RHBT can be used in various communication applications, from short-range in-room applications to longer-range outdoor applications such as industrial automation, RFID, or long-range wireless data transmission. Its low power consumption and high efficiency make it well suited for remote data acquisition and communication through many wireless protocols such as LoRa, Zigbee, and more. In addition to the long-range communication applications, the CC1200RHBT can also be used in wireless audio and video transmission, for example, for remote video surveillance.

The working principle of the CC1200RHBT is based on the Gaussian Frequency Shift Keying (GFSK) modulation technique. It generates GFSK signals by transforming the input data bit streams into GFSK waveforms. The output GFSK signal can be compared to a reference GFSK signal and bit errors can be detected which can be used to calculate the bit-error-rate. The output GFSK signal is also used to enable data recovery after radio transmission. To transmit data, the CC1200RHBT amplifies the GFSK signal and uses the integrated power amplifier for signal reception and power up the system.

To improve performance, the CC1200RHBT also features in-built on-chip filters that are used to reduce the bandwidth and frequency errors during data transmission. The on-chip filters also reduce channel mismatch errors caused by the antenna mismatch. The on-chip Low Noise Amplifier (LNA) provides the necessary gain enhancement while simultaneously reducing the current consumption of the device.

In addition, the CC1200RHBT also features advanced crystal-free calibration techniques that allow for high speed calibration to reduce errors. The advanced calibration techniques include the Dynamic Frequency Offset Estimation and Digital Automatic Gain Control. These techniques enable the calibration to be performed in a short time and with minimal system power consumption.

In conclusion, the CC1200RHBT is an integrated monolithic RF transceiver IC that operates at 915MHz, suitable for long-range communication applications and capable of providing high efficiency, low power consumption, and wide bandwidth. Its advanced features, such as the integrated power amplifier, on-chip antenna switch, and advanced calibration techniques, make it an ideal solution for wireless data communication.
