The IC-7300 is the most successful transceiver in recent years! Everyone has it, everyone wants.
With the IC-7300, Icom was the first of the three major Japanese amateur radio manufacturers to bring a genuine SDR (Software Defined Radio) transceiver for amateur radio onto the market.
The special feature of this device is that the HF signal is digitised immediately after the bandpass filter. So instead of first mixing down the received signal as with a traditional receiver, a powerful analogue-to-digital converter (ADC) is used to switch immediately to the digital level. The signal is then further processed by a special and fast digital chip (FPGA – programmable logic unit). These are the crucial components of an SDR – the AD converter and the subsequent digital logic, and of course the software used there. The reception range extends from 30 kHz to 74.8 MHz.
The transmission path is constructed in the same way: the modulation is digitised, processed by a DSP (digital signal processor) and the FPGA chip on the digital level and then converted to the analogue level, filtered and amplified. This achieves very good spectral purity and excellent phase noise values. The transmitter of the IC-7300 offers max. 100 W transmitting power (25 W in AM) and is equipped with a built-in antenna tuner.
The receiver offers excellent preselection with 15 automatically switched band filters before the AD converter. To keep losses as low as possible, high quality coil filters are installed. Due to the filtering, the AD-converter is only supplied with the signals that are to be received. This allows the dynamic range of the AD-converter to be better utilised. The result is a very good Reciprocal Mixing Dynamic Range (RMDR) of 97 dB and a 15 dB lower phase noise at 1 kHz intervals compared to the predecessor model IC-7200.
