dBm Corporation began in 1999 when the founders combined their decades of experience to provide consumers with top-quality radiofrequency (RF) test equipment and components. The dBm Corporation’s main focus is on RF test equipment, but it also creates noise signal generators, satellite link emulators, frequency converters, solid-state attenuators, and plug-ins. When an engineer needs to perform wireless link emulation involving noise, Doppler, flat fading, delay, phase shift, payload emulation, or multipath fading, he or she uses dBm RF test instruments. dBm is a brand that professional engineers and technicians can trust.
