Product details
Overview
AFIC31025NR1 from NXP Semiconductors is a 2400–3100 MHz dual-stage RF LDMOS integrated power amplifier with on-chip 50 Ω input matching, 25 W peak RF output power, 32 V DC supply rating, and integrated quiescent current temperature compensation. It supports CW and pulsed radar applications including civil S-band and maritime radar systems.
For engineers reviewing the AFIC31025NR1 datasheet, AFIC31025NR1 pinout, AFIC31025NR1 application, or AFIC31025NR1 equivalent, key selection criteria include its 25 W peak output at 2700–3100 MHz (pulse), 30 dB small-signal gain at 2400–2500 MHz (CW), 45.5% drain efficiency, TO-270WB-17 package thermal resistance of 5.85 °C/W (junction-to-case), and ESD protection per JESD22-A114 Class 1B.
Technical Context
The AFIC31025NR1 integrates two cascaded LDMOS amplifier stages-Stage 1 (driver) and Stage 2 (output)-with independent gate bias control (VGS1A/B, VGS2A/B) and dedicated bias enable terminals (VBWA/VBWB). It features monolithic 50 Ω input matching (DC-blocked) and internal thermal tracking circuitry for stable IDQ across temperature.
Designed for high-reliability RF power amplification, it operates with VDD = 32 Vdc, supports 300 µs pulse width at 15% duty cycle, and maintains no degradation under 10:1 load VSWR at 36 W CW with 3 dB input overdrive-enabling robust operation in mismatched antenna environments typical of radar transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2400–3100 MHz: fully specified performance across S-band, supporting both CW (2400–2500 MHz) and pulse (2700–3100 MHz) operation. |
| Output Power | 25 W peak (pulse), 25 W CW: enables high-power radar transmit stages without external combining or stage stacking. |
| Power Gain | 30.0 dB (CW, 2400–2500 MHz): sufficient single-stage gain to drive final PA stage with minimal preceding amplification. |
| Drain Efficiency | 45.5% (CW, 2400–2500 MHz): reduces thermal load and heatsink requirements in compact radar modules. |
| Supply Voltage | 32 Vdc max: compatible with standard high-voltage RF power supply rails used in S-band radar transmitters. |
| Junction Temp | –40 to +225 °C: supports operation in harsh environmental conditions including marine and industrial heating enclosures. |
| ESD Rating | JESD22-A114 Class 1B: provides baseline handling robustness during assembly without requiring additional external protection. |
Pinout & Package
AFIC31025NR1 is housed in a thermally enhanced plastic TO-270WB-17 package with exposed backside source terminal. The 17-pin gull-wing leadframe provides low-inductance RF I/O paths and optimized thermal conduction to the PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 15, GND pins | Ground / Source Connection | Direct connection to exposed backside source terminal; must be soldered to large copper thermal pad for optimal RθJC = 5.85 °C/W. |
| 2, 4 (RFinA, RFinB) | Differential RF Input | 50 Ω matched, DC-blocked inputs for dual-path carrier/peaking architecture; requires external 180° hybrid or balun for balanced drive. |
| 3, 9 (VGS1A, VGS1B) | Stage 1 Gate Bias | Independent bias control for driver stage; sets IDQ1(A+B) = 59 mA at VGG(Q) = 4.6–6.1 Vdc (fixture). |
| 5, 11 (VGS2A, VGS2B) | Stage 2 Gate Bias | Independent bias control for output stage; sets IDQ2(A+B) = 157 mA at VGG(Q) = 4.3–5.8 Vdc (fixture). |
| 6, 12 (RFout1/VDS2A, RFout2/VDS2B) | RF Output Terminals | High-current drain outputs; each delivers up to 25 W peak; exposed backside serves as common source return path. |
| 8, 10 (VBWA, VBWB) | Bias Enable Control | Active-high digital enable for respective channel; allows independent channel shutdown and thermal management. |
| 13, 14, 16, 17 (VDS1A, VDS1B, VDS2A, VDS2B) | Drain Supply Inputs | Separate DC supply connections per transistor segment; minimizes inter-stage coupling and improves stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MRF6VP2600HR5 | Single-stage 600 W GaN HEMT; no on-chip matching; requires external input/output networks; higher Pout but larger footprint and thermal mass. | Targeted at high-power base station macrocells (>100 W avg), not compact S-band radar modules. | Choose when >100 W average output and wideband 1.8–2.7 GHz coverage are required; avoid for space-constrained 25 W pulsed radar designs. |
| AFIC31025GNR1 | Same die, gull-wing leadform (TO-270WBG-17); identical electrical specs; differs only in lead configuration and moisture sensitivity level (MSL 3 vs MSL 1 for NR1). | Identical RF performance; selected for automated SMT placement compatibility where gull-wing leads preferred over straight leads. | Choose AFIC31025GNR1 for reflow-compatible surface-mount assembly; AFIC31025NR1 is optimized for through-hole or manual prototyping with straight leads. |
Compared with MRF6VP2600HR5 and AFIC31025GNR1, the AFIC31025NR1 uniquely combines monolithic 50 Ω input matching, dual-channel carrier-peaking topology, and TO-270WB-17 thermal packaging-making it the only drop-in solution for compact, thermally constrained 25 W S-band radar transmitters requiring minimal external components and stable bias over temperature.

FAQ
What is the maximum continuous drain voltage rating for AFIC31025NR1?
The AFIC31025NR1 has a maximum drain-source voltage rating (VDSS) of +65 Vdc, with an absolute minimum of –0.5 Vdc. However, its specified operating voltage (VDD) is rated up to +32 Vdc, and NXP recommends operation within this 0–32 Vdc range for reliable performance and lifetime. Exceeding 32 Vdc may compromise long-term reliability despite the higher absolute VDSS limit.
Does AFIC31025NR1 require external input matching networks?
No, the AFIC31025NR1 incorporates monolithic on-chip 50 Ω input matching with DC blocking, enabling direct 50 Ω system interface across its full 2400–3100 MHz operating band. This eliminates the need for external matching components such as stubs, capacitors, or transformers-reducing board area, insertion loss, and tuning complexity in radar front-end designs.
How does the quiescent current temperature compensation function in AFIC31025NR1?
The AFIC31025NR1 integrates a proprietary thermal tracking circuit that dynamically adjusts gate bias voltages (VGS1A/B, VGS2A/B) to maintain stable quiescent drain currents (IDQ1 = 59 mA, IDQ2 = 157 mA) across –40 to +150 °C case temperature. This ensures consistent RF gain, output power, and linearity without external compensation circuitry, as documented in NXP Application Note AN1977.
What is the thermal resistance junction-to-case for AFIC31025NR1?
The AFIC31025NR1 exhibits a total junction-to-case thermal resistance (RθJC) of 5.85 °C/W when measured at TC = 81 °C under DC conditions with total power dissipation of 29.3 W. This value applies to the entire device; Stage 1 contributes 1.92 °C/W and Stage 2 contributes 5.85 °C/W individually, reflecting its asymmetric power distribution and thermal design.
Is AFIC31025NR1 pin-compatible with AFIC31025GNR1?
Yes, AFIC31025NR1 and AFIC31025GNR1 share identical pin numbering, terminal functions, and electrical specifications-the only difference is the leadform: NR1 uses straight leads (TO-270WB-17), while GNR1 uses gull-wing leads (TO-270WBG-17). Both are mechanically interchangeable in footprint design, though reflow profile and handling differ due to MSL level (1 vs 3) and lead geometry.
