RF and Microwave Datasheet Specification Comparison
How to compare RF and microwave datasheets when values depend on band, test frequency, impedance, temperature, and operating mode.
Why this comparison matters
The source context determines whether values can be compared.
Gain, loss, and noise figure are frequency-dependent and may not compare at a single headline value.
dB values are logarithmic and should not be converted like linear units.
Power ratings need average, peak, pulsed, CW, and duty-cycle context.
Common datasheet labels
Labels and aliases to preserve before mapping.
Unit normalization
Normalize only when the unit family and condition are compatible.
| Property | Source formats | Canonical format | Review note |
|---|---|---|---|
| Frequency | Hz, kHz, MHz, GHz | Hz or GHz display | Range overlap is usually more useful than higher-or-lower scoring. |
| Gain and loss | dB, dBi, dBc | dB family | Keep gain, loss, shielding, and relative carrier values separate. |
| RF power | dBm, W, mW | W and dBm display | Compare only when modulation, duty cycle, and frequency are compatible. |
Worked comparison example
Originals first. Normalized values second. Review last.
| Spec | Sheet A Original | Sheet B Original | Sheet A Normalized | Sheet B Normalized | Review |
|---|---|---|---|---|---|
| Frequency range | 2 to 18 GHz | 2000 to 18000 MHz | 2 to 18 GHz | 2 to 18 GHz | Equivalent band |
| Gain | 17 dB typ at 10 GHz | 19 dB typ at 6 GHz | 17 dB typ at 10 GHz | 19 dB typ at 6 GHz | Different test frequency |
Review warnings
Values that should not be accepted automatically.
Do not compare RF performance without frequency and impedance context.
Do not treat dB, dBi, dBc, and dBm as the same unit family.
Typical gain or noise figure is not a guaranteed minimum or maximum.
How SpecCore handles this
Formula-first comparison output for engineering review.
SpecCore preserves RF units, frequency conditions, typical/min/max value type, and review flags so comparison rows remain inspectable.
