Device Overview
Designed as a RF amplifier, Qorvo AG303-63G uses the SOT-363 package. For substitution or design review, the strongest comparison points are Frequency Range (DC to 6000 MHz), Gain (20.5 dB), OIP3 (+14 dBm).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Frequency Range | DC to 6000 MHz | Defines the operating frequency or RF band that must cover the intended signal frequencies. |
| Gain | 20.5 dB | Sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions. |
| OIP3 | +26 dBm at 900 MHz | Defines third-order linearity headroom and must be compared with matching tone, frequency and bias conditions. |
| Exact Package | SOT-363 | 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. |
| Impedance | 50 Ohm | Defines RF matching compatibility with the surrounding transmission-line and matching network. |
| P1dB | +14 dBm at 900 MHz | Defines output compression headroom at the stated frequency. |
| Supply / Current | 5 V, 35 mA | Defines amplifier bias compatibility and DC demand. |
| Lifecycle / Procurement | Production | Supports current sourcing and new-design consideration. |
RF Selection Notes
DC to 6000 MHz is the stated frequency range 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.
Gain is 20.5 dB. Sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions.
The oip3 is +14 dBm; this defines third-order linearity headroom and must be compared with matching tone, frequency and bias conditions. Technical condition: at 900 MHz.
Impedance is 50 Ohm. Defines RF matching compatibility with the surrounding transmission-line and matching network.
Exact Package is SOT-363. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
Engineering Resource
For a lower-current Qorvo SOT-363 gain-block option within the DC–6 GHz family, compare AG203-63G (20 mA nominal bias, +8 dBm P1dB at 900 MHz) with this AG303-63G (35 mA nominal bias, +14 dBm P1dB at 900 MHz). Qorvo specifies different linearity and power handling for these two devices; confirm the RF gain, bias network and compression requirement before selecting another orderable.
