A buyer's primer for selecting a spectrum analyzer up to 40 GHz — frequency range and preselection, displayed average noise level, phase noise, resolution bandwidth, and whether you need a tracking generator or real-time analysis.

A practical introduction to vector network analyzers and S-parameters — what S11 and S21 mean, how many ports you need, why calibration matters, and how to specify a VNA for antenna and component characterization up to 40+ GHz.

Explore how digital power can support fault visibility, repeatable configuration and host integration, and when digital-loop flexibility is useful. Compare exact models and total integration effort; Jingmu's public power range is digital only, with analog discussed as a selection reference.

Select a digital brick DC/DC module by real input limits, output current, mechanical compatibility and thermal conditions. Read the 28 V / 48 V bus label and 80–420 W catalog span as model-specific selection information, not interchangeable ratings.

Plan digital-power integration from the exact module's interface specification: readable data, permitted settings, startup defaults, fault behavior and configuration records. Monitoring and protocol support are model-specific, not guaranteed by the digital label.

How to choose a broadband or conformal antenna for measurement and communication systems — by frequency range, polarization, radiation pattern, and mechanical environment, from 20 MHz to 110 GHz.

How to specify a low-noise or small-signal RF amplifier for a receiver front-end — noise figure, gain and flatness, linearity (P1dB/IP3), and the parameters that set system sensitivity across DC to 40 GHz.

A practical briefing on GaN solid-state power amplifiers — how GaN compares with LDMOS and GaAs, why thermal design dominates, and the efficiency-versus-linearity trade-offs for high-power RF building blocks.

How to choose microwave absorber materials — sheet, liquid and coatings — by frequency range, target reflectivity, thickness and environment, for anechoic chambers, shielding and thermal-management co-design.

How to choose EMI shielding — conductive coatings and paints, shielding films, gaskets and absorber materials — by target attenuation, frequency, geometry and environment, with attention to apertures and seams.

How to choose RF cable assemblies and connectors — attenuation versus frequency and diameter, phase stability for measurement, power handling, and selecting connector families by band and environment.

How to choose an IMU or inertial sensor for stabilization, navigation and positioning support — bias instability and drift, MEMS versus FOG technology, and the environmental limits that determine real-world performance.
