Solid state power amplifiers explained — what an SSPA is, how it works, the main types (LDMOS, GaN, GaAs), key specifications like gain, efficiency and linearity, and how SSPA compares to TWTAs and tube amplifiers.

Use our free mW to dBm conversion calculator to instantly convert between milliwatts (mW) and decibel-milliwatts (dBm). Includes formula, examples, RF power reference table, and best practices.

Understanding DC blockers — what they are, how they prevent ground loops in RF test benches, the main types (inline, bias-tee internal, capacitive), key specs, and how to integrate them into your measurement setup.

What is an EMI filter? Learn how electromagnetic interference filters work, the main types (power-line, signal-line, common-mode, differential-mode), key specifications, and how to choose the right one for your application.

An introduction to microwave limiters — what they are, how they protect sensitive receivers from high-power signals, the main types (PIN diode, Schottky, GaN), key specifications, and design considerations.

Learn how to select high-directivity directional couplers for high-power microwave systems. This guide covers directivity, coupling, isolation, power handling, thermal management, and design trade-offs.
