Product details

What this part is — Infineon BFP650FH6327XTSA1

The Infineon BFP650FH6327XTSA1 is a SiGe NPN RF transistor with 42 GHz transition frequency and 0.8 dB to 1.9 dB noise figure. It operates at 4.5 V Vceo and 150 mA Ic.

Gain and noise — what they mean for your front-end

Gain spans 11 dB to 21.5 dB. Noise figure is 0.8 dB typ at 1.8 GHz and 1.9 dB at 6 GHz.

Package and mounting — 4-TSFP

The 4-TSFP package has flat leads for reduced parasitic inductance at 42 GHz. It is surface-mount and ships in Tape & Reel or Cut Tape.

Lifecycle and sourcing

That means you can design it into a new BOM without worrying about a last-time-buy window closing. It's also ROHS3 compliant, which covers the EU and most global markets. No LTB risk, no broker-only scramble.

Frequently asked questions

What package is BFP650FH6327XTSA1 in?

It comes in a 4-TSFP surface-mount package with flat leads, also described as 4-SMD, Flat Leads.

What is the equivalent or alternative for BFP650FH6327XTSA1?

A close functional peer is the BFP640FH6327XTSA1, which offers a similar 40 GHz fT and slightly lower noise figure (0.65 dB to 1.2 dB at 1.8 GHz to 6 GHz), but with lower power handling (200 mW vs 500 mW) and lower collector current (30 mA vs 150 mA). The BFP650 is the higher-current, higher-power choice for driver stages; the BFP640 is better for ultra-low-noise receiver front-ends where current budget is tight.
