Product details
Overview
BF2030WH6814XTSA1 from NXP Semiconductors is a silicon N-channel tetrode MOSFET designed for low-noise, high-gain RF input stages up to 1 GHz. It features dual-gate architecture with independent gate control (G1 and G2), 5 V operating voltage, 1.5 dB typical noise figure at 800 MHz, 23 dB typical power gain, and SOT343 (SC-82AB) package.
For engineers reviewing the BF2030WH6814XTSA1 datasheet, BF2030WH6814XTSA1 pinout, BF2030WH6814XTSA1 application, or BF2030WH6814XTSA1 equivalent, this device serves as a precision AGC-controlled RF amplifier front-end in UHF receivers, requiring verified noise performance, gain tunability via VG2, and thermal stability up to 150 °C channel temperature.
Technical Context
This tetrode MOSFET implements a dual-gate structure where Gate 2 (G2) sets DC bias and gain level, while Gate 1 (G1) provides RF signal input and AGC control path. Its 2.4 pF typical Cg1ss and 1.3 pF Cdss enable stable impedance matching at 800 MHz with minimal feedback.
It operates under fixed 5 V drain-source voltage with VG2S adjustable from 0 to 4 V to achieve 40–50 dB gain control range; VG1S(p) is 0.5 V typ., enabling precise pinch-off tuning for linear amplification in narrowband receiver IF/RF stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-gate RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BFP181 | Single-gate LDMOS, 2.5 dB NF, 18 dB gain at 900 MHz, higher IDSS (25 mA) | Lacks G1-based AGC; requires external gain control circuitry | Preferred when cost-sensitive designs tolerate higher noise and accept added board area for control components |
| MRF901 | Discrete GaAs FET, 1.2 dB NF, 15 dB gain, 12 V operation, TO-92 package | Higher voltage requirement and through-hole mounting incompatible with dense SMT layouts | Selected only for legacy repair or ultra-low-noise lab-grade receivers where SMT density is secondary |
Compared with BFP181 and MRF901, BF2030WH6814XTSA1 uniquely integrates AGC functionality within a miniature SMT package while maintaining sub-2 dB noise and 5 V compatibility-critical for next-generation compact, battery-powered, and automotive RF receivers.

FAQ
What is the maximum safe operating voltage for BF2030WH6814XTSA1?
The absolute maximum drain-source voltage is 8 V, but the device is characterized and intended for 5 V operation per datasheet conditions. Exceeding 5 V may degrade noise figure and accelerate gate oxide wear, especially under RF stress. The 8 V rating applies only to DC transient conditions-not sustained operation.
How is AGC implemented using the dual-gate structure?
AGC is implemented by varying VG2 (Gate 2) voltage from 0 to 4 V to modulate transconductance and gain, while RF signal is applied to G1 (Gate 1). This preserves G1's high input impedance and minimizes distortion, unlike single-gate FETs requiring source degeneration or external attenuators for gain control.
Is BF2030WH6814XTSA1 compatible with lead-free reflow profiles?
Yes-the SOT343 package is RoHS-compliant and qualified for standard lead-free reflow profiles with peak temperatures up to 260 °C. Thermal resistance data (Rthchs ≤280 K/W) confirms reliable solder joint integrity and junction temperature control during JEDEC J-STD-020-compliant reflow cycles.
Why does the datasheet specify Class 2 ESD sensitivity?
BF2030WH6814XTSA1 has a Human Body Model ESD rating of 2000–4000 V due to its thin gate oxide and high-impedance G1 terminal. Handling requires grounded wrist straps, ionized air, and static-dissipative packaging-especially during PCB placement-to prevent latent damage that degrades gfs or increases leakage beyond 50 nA.
