Frequently asked questions

Where can I buy BFQ19SH6327XTSA1?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — lead time and stock are confirmed at quote time.

What is the gain of BFQ19SH6327XTSA1?

The typical gain is 7 dB at 1.8 GHz. The transition frequency is 5.5 GHz.

Is BFQ19SH6327XTSA1 RoHS compliant?

Yes, it is ROHS3 compliant.

Can BFQ19SH6327XTSA1 be used for 2.4 GHz applications?

The 5.5 GHz fT provides usable gain at 2.4 GHz, but expect lower gain than the 7 dB at 1.8 GHz — derate by roughly 3–4 dB per octave above fT/3. For higher gain at 2.4 GHz, consider the BFP193E6327HTSA1 with 8 GHz fT.
