Latest firmware garanteed installed
Icom was the first of the three major Japanese amateur radio manufacturers to bring a true SDR (Software Defined Radio) transceiver for amateur radio to the market. The IC-7610 is the further development of this successful device. It uses a high-quality, direct-sampling AD converter to convert the HF signal directly behind the antenna into digital signals. Further processing then takes place in a special digital component (FPGA, Field Programmable Gate Array). In this way, an extraordinarily high blocking dynamic range is achieved, which in the case of the IC-7610 is about 110 dB (at 2 kHz signal spacing). These good receiver characteristics are also supported by a precise oscillator that has extremely low phase noise.
The IC-7610 offers not one, but two independent receivers, continuous from 30 kHz to 60 MHz. Both are equipped with so-called DIGI-SEL filters. These work as a tracking pre-selector and have steeper edges than fixed bandpass filters. This type of filtering protects the AD converter even better against overloading by unwanted signals outside the band range.
The transmission path is constructed in the same way: the modulation is digitized, processed by a DSP (digital signal processor) and the FPGA chip on the digital level, and then converted to the analog level, filtered, and amplified. This achieves very good spectral purity and excellent phase noise values. The transmitter of the IC-7610 offers max. 100 W transmitting power and is equipped with a built-in SWR meter and antenna tuner
