Out-of-Band Suppression: Maintaining Signal Purity
nn
A critical feature of any high-performance RF component is its ability to reject unwanted signals. This power amplifier module excels with robust out-of-band spurious suppression across a broad spectrum. The specifications for this performance metric are clearly defined for two key frequency ranges, ensuring that your system does not generate interference that could affect other equipment or violate regulatory compliance.
nn
| Frequency Range | Spurious Suppression Level |
|---|---|
| 9 kHz – 1 GHz | ≤ -36 dBm / 30 kHz |
| 1 GHz – 12.75 GHz | ≤ -30 dBm / 30 kHz |
