Icom 7800
Dynamic Range

Icom's 40 years of analog RF circuit experience combined with cutting edge digital technology results in an astonishing 110dB receiver dynamic range and a +40dBm IP3 in the HF bands. A first in ham radio! To achieve this superior receiver performance, Icom's engineering team completely reviewed the whole analog circuit and matched it to the DSP units. This allowed Icom to explore new technical dimensions such as a double conversion superheterodyne system, mechanical relay BPF switching and two roofing filters.
