Product details
Overview
HPA00420RGVR 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 up to 22 dBm output power with 34% PAE at 3 V, 4.8-dB noise figure in high-gain RX mode, and supports seamless interface to TI CC24xx/CC25xx/CC2520 transceivers for ZigBee® and IEEE 802.15.4 systems.
For engineers reviewing the HPA00420RGVR datasheet, HPA00420RGVR pinout, HPA00420RGVR application, or HPA00420RGVR equivalent, this page provides verified functional block mapping, real-world current consumption (3.4 mA RX high-gain, 100 mA TX at 20 dBm), gain control logic (HGM pin), thermal resistance (RΘJA = 41.9°C/W), and layout-critical pin functions including AVDD_PA1, AVDD_LNA, and BIAS resistor termination.
Technical Context
The HPA00420RGVR implements a fully integrated 2.4-GHz RF signal path with class-AB PA, cascode LNA, and monolithic T/R switching-enabling bidirectional operation without external switches. Its internal balun converts differential RF_P/RF_N input to single-ended antenna port (ANT), while integrated matching eliminates discrete LC networks required by competing front ends.
Control is implemented via three digital inputs: EN and PAEN jointly enable power-down (100 nA) or TX/RX modes, while HGM selects LNA gain states (11 dB high-gain or 1 dB low-gain). All control pins support level-shifting for compatibility with 1.8-V logic even when VDD = 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 2400–2483.5 MHz ISM band - covers full ZigBee® and Bluetooth® Classic 2.4-GHz channels without retuning. |
| Output Power | 22 dBm maximum - enables +10 dB link budget extension over base transceivers like CC2530. |
| Noise Figure | 4.8 dB (high-gain mode) - includes T/R switch and antenna match losses, directly improving receiver sensitivity. |
| RX Current | 3.4 mA (HGM = 1), 1.7 mA (HGM = 0) - dual-gain LNA allows trade-off between sensitivity and power in battery-powered nodes. |
| TX Current | 112 mA at 0.5 dBm input, 3 V - measured on reference design; enables 20.6 dBm output with 34% PAE. |
| Power-Down Current | 0.1 μA - achieved with EN = PAEN = 0, critical for ultra-low-power wake-on-RF sensor applications. |
| Supply Voltage | 2.0–3.6 V - compatible with single-cell Li-ion, Li-Po, or dual-AA alkaline battery systems without LDO overhead. |
Pinout & Package
HPA00420RGVR uses a RoHS-compliant 4.00 mm × 4.00 mm VQFN-16 (RGV) package with exposed thermal pad requiring direct connection to solid ground plane per TI reference layout. Thermal resistance is RΘJA = 41.9°C/W (still air), RΘJB = 20.4°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RF_P / RF_N | Differential RF interface | Connects directly to CC24xx/CC25xx transceiver RF I/O; requires no external balun or matching components. |
| RXTX | Transmit/receive mode control | Driven by transceiver's RXTX pin; determines internal T/R switch state and enables PA/LNA path selection. |
| PAEN / EN | Digital enable inputs | Joint logic controls operational mode: both low = 100-nA shutdown; PAEN high + EN low = TX; EN high + PAEN low = RX. |
| HGM | LNA gain select | HGM = 1 → 11 dB LNA gain (RX high-sensitivity); HGM = 0 → 1 dB gain (RX low-noise bypass for strong signals). |
| ANT | Single-ended antenna port | 50-Ω matched RF output; connects directly to PCB antenna or SMA connector without external matching. |
| AVDD_PA1 / AVDD_PA2 | PA supply rails | PCB traces serve as inductive loads for PA bias; layout must follow TI's recommended trace width/length per SWRU190. |
| AVDD_LNA | LNA supply rail | 2–3.6 V supply with dedicated decoupling; trace inductance sets LNA bias point and impacts noise figure stability. |
| BIAS | PA bias current adjust | External resistor to GND sets PA quiescent current - critical for optimizing linearity vs. efficiency trade-off. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PA + LNA + T/R switch | Eliminates ≥12 external components (inductors, capacitors, balun, discrete switches) versus discrete front-end solutions. |
| On-chip balun and matching | Removes need for external 2.4-GHz balun IC or discrete LC matching network - reduces BOM count and layout area by >30%. |
| Dual-gain LNA with HGM control | Enables dynamic RX sensitivity adjustment: 4.8-dB NF at 11 dB gain for weak signals; 1-dB gain for strong interference rejection. |
| Ultra-low power-down current | 0.1 μA shutdown minimizes leakage in battery-operated wireless sensor nodes with long sleep intervals (e.g., hourly wake-up). |
| Thermal performance optimized | Exposed die attach pad + low RΘJB (20.4°C/W) allows sustained 22-dBm output on 2-layer PCBs without heatsinking. |

FAQ
What is the primary function of HPA00420RGVR in a 2.4-GHz wireless system?
HPA00420RGVR serves as a complete RF front-end amplifier that boosts transmit output power to 22 dBm and improves receive sensitivity via a 4.8-dB-noise-figure LNA. It integrates PA, LNA, T/R switch, balun, and matching network - eliminating external RF components required by base transceivers like CC2530 or CC2520. This integration reduces design risk and accelerates development of ZigBee®, Thread, and proprietary 2.4-GHz sensor networks.
How does the HGM pin affect HPA00420RGVR performance in receive mode?
The HGM (High-Gain Mode) pin configures the LNA gain state of HPA00420RGVR: HGM = 1 enables 11 dB gain with 4.8-dB noise figure for maximum sensitivity; HGM = 0 reduces gain to 1 dB, lowering current to 1.7 mA and improving linearity against strong interferers. This dual-mode operation allows adaptive RX optimization in dynamic RF environments - a capability confirmed in Table 4-4 of the SWRS070B datasheet for HPA00420RGVR.
Can HPA00420RGVR be used with non-TI transceivers such as Nordic nRF24L01+?
HPA00420RGVR is electrically compatible with any 2.4-GHz transceiver offering differential RF_P/RF_N I/O and 1.8-V–3.6-V logic-level control signals, but TI's reference designs and timing specifications (e.g., 12-μs RX mode switching) are validated only with CC24xx, CC25xx, and CC2520 families. Interfacing with nRF24L01+ requires custom layout validation of RXTX timing, impedance matching, and PAEN/EN sequencing - no official support or characterization data exists for that combination in the HPA00420RGVR documentation.
What is the role of the BIAS pin on HPA00420RGVR, and how is it configured?
The BIAS pin on HPA00420RGVR sets the quiescent current of the power amplifier using an external resistor to ground. Per Section 3.1 and Figure 5-1 of SWRS070B, a 4.3-kΩ resistor (RK73H1ETTP4301F) yields optimal PAE and linearity for 22-dBm output. Changing this resistor alters PA bias point - affecting output power, efficiency, and OIP3 - and must be re-characterized per application requirements. The BIAS pin has no internal pull-up/down and must never be left floating.
Does HPA00420RGVR require external matching components for the antenna port?
No, HPA00420RGVR includes a fully integrated matching network and balun, making the ANT pin 50-Ω matched for direct connection to PCB antennas, chip antennas, or SMA connectors. TI's CC2591EM evaluation module (SWRU190) confirms zero external matching components are needed at the antenna port - a key differentiator from PA-only alternatives like SKY66112-364LF. Any added external matching degrades performance and voids the specified 22-dBm output and 4.8-dB noise figure.
