Innovative IC-7300 HF/50/70MHz Transceiver Launched at Tokyo Ham Fair 2015
Icom Inc. had a huge amount of interest on is stand at the Tokyo Ham Fair 2015 with the unveiling of the
IC-7300 HF/50/70MHz Transceiver. The launch, which caught most people by
surprise, saw the manufacturer introduce a new base station transceiver
incorporating the latest RF direct sampling system, a first for an Amateur
radio transceiver*.
The IC-7300 transceiver, an aesthetically, attractive
looking base station, features a 4.3 inch touch screen colour TFT LCD screen
with a high performance real time band scope.
A first for an Amateur radio transceiver, the IC-7300 uses a
RF Direct Sampling System, a technology normally seen in Software Defined
Radios. RF signals are mostly processed through the FPGA (Field-Programmable
Gate Array), rather than by physical devices enabling high performance
real-time spectrum scope in a compact body.
The IC-7300 includes a built-in integrated wide-frequency
Automatic Antenna Tuner making ideal for field operation. The radio provides
100 watts output power on HF/50MHz bands and 50 watts on 70MHz (European
versions only).
Icom Inc. has produced a
pre-release leaflet for the IC-7300 which you can download from this page. This
information is preliminary and a full document will be made available nearer to
the product's launch. SoRF Direct sampling system — a first in Amateur Radio*
Instead of the
conventional superheterodyne system, the IC-7300 utilizes the RF direct
sampling system — a first in an amateur radio transceiver. This technology is seen
in Software Defined Radios and other radio equipment. RF signals are mostly
processed through the FPGA (Field-Programmable Gßate Array), making it possible
to eliminate physical mixer and filter devices and offer a high performance
real-time spectrum scope in a compact body.

Class leading phase noise characteristics
Overcoming cost and
performance limitations of the superheterodyne system, the RF direct sampling
system pursues ideal high performance phase noise. As the result, compared to
the IC-7200, the IC-7300’s phase noise characteristics are improved about 15dB
(at 1kHz frequency offset). This superior phase noise reduces noise components
in both receive and transmit signals.* Researched by Icom, among major amateur radio manufactures.
