Rendimiento RF
No se propone una clasificación global. Compare definición de medida y punto operativo, use límites aplicables y un plan de ensayos aprobado por el cliente.
Las guías enlazadas en inglés ayudan a definir requisitos, riesgos de compras y revisión técnica del cliente. Las etiquetas describen el contenido, no proyectos ya realizados.

- RF Performance Test Conditions
Carry the conditions with the number.
| Metric | Conditions to preserve | Decision boundary |
|---|---|---|
| Frequency range | Exact device/version and RF path; intended channel and matching network. | Documented chip coverage is not permission for every regional channel. |
| Output power | Measurement plane, frequency, waveform, supply/bias, load, duty cycle and temperature. | Conducted output and system radiated power are different quantities. |
| Receiver sensitivity | Modulation, bandwidth, spreading factor/coding, data rate, packet setup, PER/BER criterion and temperature. | A smaller number at a different modem setting is not a fair winner. |
| Noise figure | Frequency band, gain state, source/load conditions, bias, case temperature and measurement setup. | Use the actual LNA and system context; do not transfer a typical NF to another part. |
| Power consumption | Supply, regulator mode, active/idle/sleep states, transition times, reporting schedule and external circuitry. | One chip-current figure does not predict product battery life. |
| Interface and supply | Exact logic thresholds, timing, pin functions, startup and permitted operating range. | SPI compatibility and a shared nominal supply do not establish interchangeability. |
A specific conditions example
SX1276/77/78/79 Rev. 7 §2.5.5 defines default LoRa conditions including a 3.3 V supply, 25°C, 125 kHz bandwidth, SF12, error-correction setting 4/6 and 1% PER. Packet configuration, matching and row-specific exceptions also matter. These defaults belong to that table; they are not assigned to SX1262, SX1268 or another device.
For ADL8108 Rev. 0, the specification tables state band-specific conditions including supply, bias setting and case temperature. The tables and curves must be read together rather than treating a feature-page noise figure as a universal value.
