MRF9331LT1MOTOROLA RF DEVICE DATA
The RF Line
Designed primarily for use in low power amplifiers to 1.0 GHz. Ideal for
pagers and other battery operated systems where low power consumption is
critical.
• Low Power Consumption Characterized for IE = 0.1 to 1.0 mA
• High Current–Gain — Bandwidth Product —
fT = 5.0 GHz (Typ) @ IC = 1.0 mAdc
• Low Noise Figure and High Power Gain @ f = 1.0 GHz —
NF(matched) = 2.5 dB (Typ)
GNF(matched) = 12.5 dB (Typ)
• Guaranteed RF Parameters
• Surface Mounted SOT–143 Offers Improved RF Performance
Lower Package Parasitics
High Gain
• Available in tape and reel packaging:
T1 suffix = 3,000 units per reel
