Product details
Overview
CC2591RGVT from Texas Instruments is a 2.4-GHz RF front-end IC integrating PA, LNA, T/R switch, balun, and matching network in a single QFN-16 package. It delivers +22 dBm output power, 4.8-dB noise figure (high-gain mode), 11-dB receive gain, 3.4-mA RX current (HGM), and operates from 2–3.6 V. It extends link budget for IEEE 802.15.4/ZigBee® transceivers such as CC2430, CC2530, and CC2520.
For engineers reviewing the CC2591RGVT datasheet, CC2591RGVT pinout, CC2591RGVT application, or CC2591RGVT equivalent, key selection considerations include its dual-mode LNA gain control (HGM pin), 100-nA power-down current, integrated antenna interface (ANT), and seamless interoperability with TI's 2.4-GHz SoC transceivers via RF_P/RXTX/RF_N signaling.
Technical Context
The CC2591RGVT implements a fully integrated RF signal path: transmit chain includes a 22-dBm Class-AB PA with 34% PAE at 3 V, while receive path features a low-noise amplifier with selectable 11-dB (HGM=1) or 1-dB (HGM=0) gain and 4.8-dB noise figure including T/R switch and antenna match. Its internal balun enables direct differential-to-single-ended conversion between transceiver and antenna ports.
Control logic uses four digital inputs-PAEN, EN, HGM, and RXTX-to configure power-down, TX, RX high-gain, and RX low-gain modes. Mode transitions are fast: 12 μs (RX power-down) and 1 μs (TX power-down). All supply pins (AVDD_PA1, AVDD_PA2, AVDD_LNA, AVDD_BIAS) require 2–3.6 V and serve as inductive loads for respective RF stages.

Pinout & Package
CC2591RGVT uses a 4.00 mm × 4.00 mm RoHS-compliant VQFN-16 (RGV) package with exposed thermal pad. The pad must be soldered to a solid ground plane using multiple low-inductance vias for optimal RF performance and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 12, 14 | GND | Secondary ground connections - must be shorted to exposed die attach pad on top PCB layer. |
| 2, 10 | AVDD_PA1 / AVDD_PA2 | PA power supplies - PCB traces serve as inductive loads; require local 10-pF/1-nF decoupling per TI reference design. |
| 3 | RXTX | Transmit/receive mode control input - accepts 1.3–3.6 V logic; interfaces directly with CC24xx/CC25xx RXTX pin. |
| 4, 5 | RF_P / RF_N | Differential RF interface to transceiver - connects to CC2430/CC2530/CC2520 RFIO pins with no external balun needed. |
| 6, 7 | PAEN / EN | Digital enable controls - PAEN activates PA; EN enables entire device; both low = power-down (100 nA). |
| 11 | ANT | Single-ended antenna port - integrates balun and matching; requires no external components for 50-Ω antenna interface. |
| 13 | AVDD_LNA | LNA power supply - trace serves as inductive load; decoupled with 10-pF/1-nF caps per reference layout. |
| 15 | BIAS | PA bias current setting - external resistor (e.g., 4.3 kΩ) to GND sets optimal PA operating point. |
| 16 | AVDD_BIAS | Bias circuit supply - powers internal bias generation; requires 2–3.6 V and local decoupling. |
| HGM | 7 | LNA gain select - HGM=1 enables 11-dB gain (high sensitivity); HGM=0 enables 1-dB gain (high linearity). |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SX1212-EVB | Lower max output (+17 dBm), higher NF (6.5 dB), requires external balun and matching - larger BOM and layout complexity. | Targeted at narrowband sub-GHz systems; lacks native 2.4-GHz ISM optimization and ZigBee® timing alignment. | Choose only if migrating from Semtech ecosystem or requiring sub-GHz fallback capability. |
| SKY65111-368LF | Higher output (+25 dBm), but no integrated LNA or T/R switch - requires companion LNA (e.g., SKY65162) and external switching. | Designed for Wi-Fi/BT coexistence; lacks HGM-controlled gain modes and direct CC25xx interface logic. | Select when prioritizing peak TX power over integration level and system-level power efficiency. |

FAQ
What is the primary function of CC2591RGVT in a wireless system?
The CC2591RGVT functions as a complete 2.4-GHz RF front-end IC that enhances both transmit output power (+22 dBm) and receive sensitivity (4.8-dB noise figure) for TI's CC24xx/CC25xx/CC2520 transceivers. It integrates PA, LNA, T/R switch, balun, and matching network - eliminating six or more discrete components and enabling compact, high-performance wireless designs without external RF tuning.
How does the HGM pin affect CC2591RGVT operation?
The HGM (High-Gain Mode) pin on CC2591RGVT selects between two LNA gain states: HGM = 1 enables 11-dB receive gain for maximum sensitivity in weak-signal environments; HGM = 0 reduces gain to 1 dB for improved linearity and blocking immunity in high-interference scenarios. This real-time control allows adaptive RX performance without changing hardware or firmware timing parameters.
Can CC2591RGVT be used with non-TI transceivers?
CC2591RGVT is electrically compatible with any 2.4-GHz transceiver supporting differential RF_P/RF_N interface and 1.3–3.6-V logic control levels, but its control timing and pin mapping are optimized for TI's CC24xx, CC25xx, and CC2520 families. Interfacing with non-TI devices requires verifying RXTX/PAEN/EN/HGM timing alignment and may necessitate external level-shifting or logic translation not required with TI SoCs.
What is the role of the BIAS pin on CC2591RGVT?
The BIAS pin on CC2591RGVT sets the quiescent current of the internal power amplifier via an external resistor to ground - typically 4.3 kΩ for optimal 22-dBm output and 34% PAE at 3 V. Adjusting this resistor allows fine-tuning of PA linearity, efficiency, and thermal behavior without modifying the core CC2591RGVT silicon or layout.
Does CC2591RGVT require external matching components?
No - CC2591RGVT integrates all critical RF matching components, including balun, PA/LNA matching networks, and T/R switch. The ANT pin connects directly to a 50-Ω antenna, and RF_P/RF_N connect directly to TI transceivers' differential RFIO ports. Only local decoupling capacitors (10 pF + 1 nF per supply pin) and the BIAS resistor are required per TI's CC2591EM reference design.
