HF-Leistungsparameter

Frequenz, Ausgangsleistung, Empfindlichkeit, Rauschzahl und Stromaufnahme mit ihren jeweiligen Bedingungen lesen.

Themenbereiche

HF-Leistungsparameter

Es wird keine pauschale Rangfolge erstellt. Messdefinition und Betriebspunkt abgleichen, belastbare Grenzen verwenden und einen kundenseitig freigegebenen Systemtest planen.

Die verlinkten englischen Leitfäden helfen bei Anforderungsdefinition, Beschaffungsrisiken und Planung der kundenseitigen technischen Prüfung. Die Themen beschreiben den Inhaltsumfang, keine abgeschlossenen Projekte.

Behandelte Fragen

  • Frequency Range
  • Output Power
  • Receiver Sensitivity
  • Noise Figure
  • Power Consumption
  • RF Performance Test Conditions
English technical reference

Carry the conditions with the number.

MetricConditions to preserveDecision boundary
Frequency rangeExact device/version and RF path; intended channel and matching network.Documented chip coverage is not permission for every regional channel.
Output powerMeasurement plane, frequency, waveform, supply/bias, load, duty cycle and temperature.Conducted output and system radiated power are different quantities.
Receiver sensitivityModulation, 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 figureFrequency 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 consumptionSupply, 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 supplyExact 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.
