LoRa Network Planning and RF Site Surveys: A Practical Engineering Guide
LoRa Network Planning and RF Site Surveys: A Practical Engineering Guide Deploying a LoRa network is far more than selecting a gateway and scattering sensors across a site. Behind every reliable, low-power wide-area network (LPWAN) deployment is a rigorous engineering process—one that starts long before a single packet is transmitted. RF site surveys, propagation modeling,

Design of Radio Low Noise Amplifiers (LNAs)
Introduction to LNAs A Low Noise Amplifier (LNA) is an electronic amplifier designed to boost very weak RF signals while adding as little additional noise as possible (Low-noise amplifier – Wikipedia). In a receiver chain, the LNA is typically the first active component after the antenna ( FAQ | ShareTechnote). Its primary role is to
SiGe Low Noise Amplifier (LNA) Topologies and Architectures
Introduction A low-noise amplifier (LNA) is a critical front-end component in RF receivers, responsible for amplifying very weak incoming signals while adding as little noise as possible. LNAs are characterized by key metrics including noise figure (NF), gain, linearity (typically specified by intercept points or compression point), and power consumption. Silicon-Germanium (SiGe) technology (often SiGe
Introduction to SDR
Introduction to SDR Software Defined Radio (SDR) is a radio communication technology where many signal processing components that were traditionally built in hardware are instead implemented in software (Software-defined radio – Wikipedia) (Software Defined Radio: Past, Present, and Future – NI). In a conventional radio, elements like filters, mixers, modulators, demodulators, and detectors are physical
