14 GHz fT, 17.5 dB gain — LNA front-end fit
The BFR340L3E6327XTMA1 is an NPN RF transistor from Infineon with a 14 GHz transition frequency and 17.5 dB gain at 1.8 GHz, making it a candidate for low-noise amplifier stages in the 1.5–2.5 GHz band — cellular, ISM, or GPS front-ends. Noise figure is 1.15 dB at 1.8 GHz, which keeps the cascaded noise budget tight enough for a sub-2 dB receiver NF when the LNA is the first active stage. Collector current is capped at 10 mA and Vceo at 9 V — this is a small-signal device, not a driver. The operating point for best NF typically falls around 5 mA, where hFE is specified at 90 minimum.
PG-TSLP-3-1 footprint and thermal reality
The PG-TSLP-3-1 package (SOT-883 compatible) is a 0.4 mm pitch leadless package with no exposed thermal pad — all heat dissipates through the collector terminal and the PCB copper. The 60 mW max power rating assumes a standard FR-4 footprint with minimal copper pour.
Active lifecycle, ROHS3 — no sourcing surprises
Infineon lists the BFR340L3E6327XTMA1 as Active with no NRND or last-time-buy flags — it remains a valid design-in choice for new RF front-end boards. ROHS3 compliant means no substance exemptions expire on a fixed calendar — the part stays compliant with EU and China RoHS without a compliance re-spin.
