How should you learn RF design?

From RF Design Wiki · By the RF Design Wiki editorial team · Published October 21, 2026 · Last reviewed October 21, 2026 · How we research

Learn RF design in layers: first units and noise (dB, dBm, thermal noise), then transmission lines and the Smith chart, then S-parameters and matching, then the active blocks (amplifiers, mixers, oscillators, PLLs), then antennas and link budgets, and finally layout, EMC and measurement. Each layer depends on the one before it.

What should you learn first?

What comes next?

Receivers: noise figure, linearity, LNAs, mixers, architectures.
Transmitters: PAs, efficiency, linearization.
Frequency generation: oscillators, phase noise, PLLs.
Radiation: antennas, link budgets.
Hardware: PCB layout, EMC, VNA and spectrum analyzer use.

Which textbooks are standard?

Pozar’s Microwave Engineering for passive and microwave circuits;^[1] Razavi’s RF Microelectronics^[2] and Lee’s The Design of CMOS Radio-Frequency Integrated Circuits^[3] for transceiver ICs; Balanis for antennas;^[4] Cripps for power amplifiers;^[5] Ott for EMC.^[6] See RF textbooks.

Frequently asked questions

How long does it take to learn RF design?

Fundamentals can be learned in months; competence in layout, measurement and debugging typically takes years of bench experience.

Can I learn RF without lab equipment?

Partly. Free circuit and EM simulators help, but low-cost VNAs and SDRs make hands-on practice affordable.

Is math required?

Complex numbers, logarithms and basic calculus are essential; field theory is needed for antennas and EM.
