Product details

45 GHz SiGe:C NPN for LNA and driver stages

The Infineon BFP520H6327XTSA1 is a silicon-germanium carbon (SiGe:C) NPN RF bipolar transistor in a SOT-343 package. It delivers 22.5 dB gain with a noise figure of 0.95 dB at 1.8 GHz, making it a strong candidate for low-noise amplifier front-ends in cellular infrastructure, GPS receivers, and ISM-band radios. The 45 GHz transition frequency keeps gain flat well into Ku-band, so it also works in satellite down-converters and point-to-point radio driver stages.

3.5 V Vceo — design the rail first

Collector-emitter breakdown is 3.5 V maximum. The 40 mA collector current limit suits low-to-medium power stages.

Frequently asked questions

Where can I buy BFP520H6327XTSA1?

This part is sourced through independent distribution channels. Submit an RFQ for current pricing and lead time.

What are alternatives to BFP520H6327XTSA1?

The BFP420 is an earlier generation with lower fT (25 GHz) and higher NF. BFP520 is the higher-performance replacement. No pin-compatible second source is listed in the Infineon cross-reference.

Can BFP520H6327XTSA1 replace BFP420?

The BFP520 is a direct performance upgrade over the BFP420, with higher gain and lower noise figure. Pin compatibility should be verified against the respective datasheets.
