Product details
Overview
CC1020-RTB1 from Texas Instruments is a true single-chip UHF RF transceiver for narrowband systems, operating in 402–470 MHz and 804–930 MHz bands with programmable output power up to +10 dBm (433 MHz), –118 dBm sensitivity at 12.5 kHz channel spacing, and 153.6 kBaud data rate using OOK/FSK/GFSK modulation. It integrates low-IF receiver, digital RSSI, carrier sense, and crystal oscillator temperature compensation without TCXO.
For engineers reviewing the CC1020-RTB1 datasheet, CC1020-RTB1 pinout, CC1020-RTB1 application, or CC1020-RTB1 equivalent, this device supports EN 300 220/FCC Part 15/ARIB STD-T67 compliance, requires no external IF filter, delivers low RX current (19.9 mA), and enables frequency-hopping and multichannel narrowband telemetry in space-constrained designs.
Technical Context
The CC1020-RTB1 implements a low-IF receiver architecture with integrated image rejection mixer, programmable digital channel filter (9.6–307.2 kHz bandwidth), and I/Q gain/phase calibration for >49 dB image rejection. Its PLL-based frequency synthesizer supports <300 Hz step resolution in 402–470 MHz and <600 Hz in 804–930 MHz bands, enabling crystal drift compensation via AFC.
Transmit path includes integrated PA with programmable output power, OOK/FSK/GFSK modulation, and built-in bit synchronizer. The 4-wire SPI interface (PSEL/PCLK/PDI/PDO) configures all operating parameters-including data rate, frequency, modulation type, and receiver filter bandwidth-enabling flexible system integration with microcontrollers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar narrowband UHF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC1120RHBR | Successor device with higher sensitivity (–120 dBm), wider frequency range (27–1050 MHz), and improved spurious performance; requires different layout and firmware adaptation. | Supports sub-GHz IoT protocols (e.g., Wireless M-Bus) requiring >10-year battery life and enhanced coexistence in dense RF environments. | Select CC1120RHBR for new designs needing extended range, multi-band flexibility, or future-proofing against CC1020 end-of-life. |
| SI4463-C2A-GMR | Higher output power (+20 dBm), integrated PA, and lower RX current (13.7 mA); uses different SPI register map and antenna matching requirements. | Better suited for long-range telemetry (>5 km) and battery-powered repeaters where transmit power and efficiency are critical. | Choose SI4463-C2A-GMR when regulatory-compliant +20 dBm output or ultra-low RX current is mandatory, accepting revised RF front-end design. |
Compared with CC1020-RTB1, CC1120RHBR offers superior sensitivity and frequency agility but demands updated hardware/firmware, while SI4463-C2A-GMR delivers higher output power and lower RX current at the cost of increased complexity in matching network design and register-level configuration.

FAQ
What is the maximum data rate supported by the CC1020-RTB1?
The CC1020-RTB1 supports a maximum data rate of 153.6 kBaud in NRZ mode, equivalent to 76.8 kbps in Manchester coding. This rate is achievable with 500 kHz channel spacing and ±72 kHz frequency deviation, as verified in TI's SWRS046I datasheet Section 4.4. The CC1020-RTB1 maintains reliable demodulation at this rate using its programmable digital channel filter and integrated bit synchronizer.
Does the CC1020-RTB1 require an external TCXO for stable operation?
No, the CC1020-RTB1 does not require an external TCXO. Its programmable frequency synthesizer and AFC (Automatic Frequency Control) feature enable crystal temperature drift compensation using standard ±20 ppm crystals, satisfying EN 300 220 12.5 kHz channel requirements without added cost or board space. The CC1020-RTB1 achieves this through fine-step PLL tuning and real-time correction based on RSSI and carrier sense feedback.
What package type and dimensions does the CC1020-RTB1 use?
The CC1020-RTB1 uses a 7.0 mm × 7.0 mm VQFNP-32 (QFN) package with an exposed die-attach pad that must be soldered to a solid ground plane. This mechanical construction is specified in TI's SWRS046I datasheet Section 8.1 and provides thermal and electrical grounding essential for RF stability. The CC1020-RTB1's compact footprint supports high-density PCB layouts in space-constrained wireless modules.
Which regulatory standards does the CC1020-RTB1 support out of the box?
The CC1020-RTB1 is designed to meet EN 300 220 (Europe), FCC CFR47 Part 15 (USA), and ARIB STD-T67 (Japan) without hardware modification. Verified radiated spurious emissions (<–60 dBm), adjacent channel power (–46 dBc at 12.5 kHz), and selectivity (41 dB) are documented in Sections 4.4–4.5 of the SWRS046I datasheet. The CC1020-RTB1 achieves compliance using its integrated filtering, calibrated image rejection, and programmable output power limiting.
How does the CC1020-RTB1 handle interference in crowded RF environments?
The CC1020-RTB1 combats interference via 32–37 dB adjacent channel rejection, >50 dB blocking immunity at ±1 MHz offset, and 40 dB spurious rejection across 100 MHz–2 GHz. Its programmable digital channel filter (9.6–307.2 kHz), I/Q calibration for >49 dB image rejection, and carrier sense circuit allow dynamic channel assessment before transmission. These features are validated in SWRS046I Section 4.5 and enable robust operation in environments with Wi-Fi, GSM, or other ISM band emitters near the CC1020-RTB1.
