Device Overview
SBB4089Z is a Qorvo RF amplifier in a SOT-89 package. Selection of this exact part is driven primarily by Frequency Range (50 MHz to 6000 MHz), Gain (17.0 dB), Noise Figure (5.5 dB).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Frequency Range | 50 MHz to 6000 MHz | Defines the operating frequency or RF band that must cover the intended signal frequencies. |
| Gain | 17.0 dB | Sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions. |
| Noise Figure | 5.5 dB | Defines the device contribution to receiver noise and must be compared at matching frequency and bias conditions. |
| P1dB | 19.3 dBm (at 1950 MHz) | Defines output compression headroom and must be compared at matching frequency and bias conditions. |
| OIP3 | 35.2 dBm (at 1950 MHz) | Defines third-order linearity headroom and must be compared with matching tone, frequency and bias conditions. |
| Supply Voltage | 5 V | Defines compatibility with the available board power rail and required bias range. |
| Supply Current | 92.0 mA | Defines DC current demand and therefore contributes to amplifier power consumption and thermal load. |
| Impedance | 50 Ohm | Defines RF matching compatibility with the surrounding transmission-line and matching network. |
| Exact Package | SOT-89 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Rf Function | RF amplifier | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
RF Selection Notes
For frequency range, 50 MHz to 6000 MHz is the approved value. Defines the operating frequency or RF band that must cover the intended signal frequencies. RF amplifier is the stated rf function value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
For gain, 17.0 dB is the approved value. Sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions. For noise figure, 5.5 dB is the approved value. Defines the device contribution to receiver noise and must be compared at matching frequency and bias conditions.
For p1db, 19.3 dBm is the approved value. Defines output compression headroom and must be compared at matching frequency and bias conditions. Technical condition: at 1950 MHz. At 35.2 dBm, the oip3 defines third-order linearity headroom and must be compared with matching tone, frequency and bias conditions. Technical condition: at 1950 MHz.
At 5 V, the supply voltage defines compatibility with the available board power rail and required bias range. Supply Current is 92.0 mA. Defines DC current demand and therefore contributes to amplifier power consumption and thermal load. Impedance is 50 Ohm. Defines RF matching compatibility with the surrounding transmission-line and matching network.
At SOT-89, the exact package determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
