Device Overview
Qorvo QPA0812 is an exact-order RF amplifier supplied in 20-pin QFN, 4 x 3 mm. Selection of this exact part is driven primarily by Frequency Range (8.5 to 10.5 GHz), Gain (34.4 dB), Output Power (30.8 dBm).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Frequency Range | 8.5 to 10.5 GHz | Defines the operating frequency or RF band that must cover the intended signal frequencies. |
| Gain | 34.4 dB | Sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions. |
| Output Power | 30.8 dBm | Defines available output-power headroom under the stated operating conditions; compare it at the same frequency, modulation/load and bias. |
| Exact Package | 20-pin QFN, 4 x 3 mm | 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. |
| Power Added Efficiency | 48.2 % | Defines a selection-critical engineering characteristic that a compatible substitute must preserve under the stated conditions. |
| Supply Current | 156 mA | Defines DC power and thermal burden on the bias or supply rail. |
| Impedance | 50 Ohm | Defines RF matching compatibility with the surrounding transmission-line and matching network. |
RF Selection Notes
For frequency range, 8.5 to 10.5 GHz is the approved value. Defines the operating frequency or RF band that must cover the intended signal frequencies. Rf Function is RF amplifier. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
At 34.4 dB, the gain sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions.
Output Power is 30.8 dBm. Defines available output-power headroom under the stated operating conditions; compare it at the same frequency, modulation/load and bias.
156 mA is the stated supply current value. Defines DC power and thermal burden on the bias or supply rail. Impedance is 50 Ohm. Defines RF matching compatibility with the surrounding transmission-line and matching network.
For exact package, 20-pin QFN, 4 x 3 mm is the approved value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
The power added efficiency is 48.2 %; this defines a selection-critical engineering characteristic that a compatible substitute must preserve under the stated conditions.
