Device Overview
Qorvo SBB5089Z is a general-purpose RF amplifier in SOT-89 for 50 to 6000 MHz operation. Key published parameters include 20.1 dB gain, 4.2 dB noise figure, 20.4 dBm P1dB and 35 dBm OIP3 at the manufacturer-stated conditions.
Selection-Critical Data
| Parameter | Confirmed Data | Engineering Relevance |
|---|---|---|
| Frequency range | 50 to 6000 MHz | Must cover the intended RF signal band. |
| Gain | 20.1 dB | Sets the available small-signal gain budget. |
| Noise figure | 4.2 dB | Contributes directly to receiver noise performance. |
| P1dB | 20.4 dBm | Indicates output compression headroom. |
| OIP3 | 35 dBm | Indicates third-order linearity headroom. |
| Supply voltage | 5 V | Must match the RF bias rail. |
| Package | SOT-89 | Defines PCB footprint and assembly compatibility. |
Procurement Note
Qorvo lists SBB5089Z as Discontinued. For an existing design, sourcing continuity should be checked before committing to additional production volume.
For a lower-gain, lower-compression-power RF gain block in the same Qorvo 50–6000 MHz SOT-89 group, compare SBB3089Z with this SBB5089Z. Qorvo’s product data lists 16.4 dB gain and 15.2 dBm output P1dB for SBB3089Z, versus 20.1 dB and 20.4 dBm for SBB5089Z at the published manufacturer conditions. Verify frequency, bias current and RF matching for the actual design; these specifications do not establish direct interchangeability.
