The Pattern of Perfection Continues 

110dB dynamic range and 40dBm 3rd order Intercept Point (IP3) 
The IP3 performance of a radio can be improved by sacrificing sensitivity, but Icom considers this a poor choice. To achieve REAL high-performance, Icom reviewed all of the analog receiver circuitry. The IC-7700 employs mechanical relay BPF 
switching, a digitally tuned pre-selector, and three Hi-spec 1st IF filters (roofing filter) in a Dynamic range characteristics (in 14MHz band) clean and simple double-conversion superheterodyne design. By balancing the analog and DSP 
functions, the IC-7700 provides superior sensitivity simultaneously with a superb dynamic range of 110dB, and 40 dBm IP3 (even in USB mode with 2.4 kHz filter bandwidth).. 

Better than 110dBm 2nd order intercept point (IP2) 
An IP2 point of more than 110 dBm* means the 2nd order distortion from strong broadcast stations will be completely eliminated. The endless pursuit of leading analog circuit engineering makes it possible to achieve this leading edge level 
of performance. 
* Measurements were made using custom equipment, due to the limits of normal signal generators (SG) and duplexers to 85 dBm. The IP2 figure is a typical value. 

Double conversion superheterodyne system 
While multiple IF stages can become a source of distortion products and spurious responses, the IC-7700 utilizes Icom’s original image-rejection mixers in a simple double conversion superheterodyne. This reduces distortion and p
