Knowledge Base
Engineering reference tables for RF and microwave work, each on its own page with selection notes and answers to the questions engineers actually ask. All content is published for reference only — no component models, specifications or pricing are included.
Reference topics
- RF & Microwave Frequency Bands (L to Ka)
Reference chart of RF and microwave band designations with approximate frequency ranges and typical uses, from HF to 300 GHz. Engineering reference only.
- S-Parameters Explained: S11, S21, S12, S22
What scattering parameters mean, how to read S11, S21, S12 and S22, and how they are measured with a vector network analyzer. Engineering reference only.
- RF Connector Frequency Limits: SMA, N, 2.92 mm
Typical upper frequency limits for common RF connectors, with mating notes. Choose by highest operating frequency first, then by the interface in your system.
