Designed p rimarily f or use in t he high–gain, low–noise small–signal
amplifiers for operation up to 3.5 GHz. Also usable in applications requiring fast
switching times.

• High Current Gain–Bandwidth Product —

fT = 3.4 GHz (Typ) @ IC = –35 mAdc (MMBR521LT1)
fT = 4.2 GHz (Typ) @ IC = –50 mAdc (MRF5211LT1)

• Low Noise Figure @ f = 1.0 GHz —

NF

(matched)

= 2.5 dB (Typ) (MMBR521LT1)

NF

(matched)

= 2.8 dB (Typ) (MRF5211LT1)

• High Power Gain — G

pe (matched)

= 11 dB (Typ)

• Guaranteed RF Parameters

• Surface Mounted SOT–23 (MMBR521LT1) & SOT–143 (MRF5211LT1)

Offer Improved RF Performance

Lower Package Parasitics
Higher Gain

• Available in tape and reel packaging options:
