RF Direct Sampling Takes You to the Next Level with Advanced RMDR and True Dual Receive

The SDR You Have Asked For
Faint signals are no longer a challenge for DXers and Contesters worldwide, with the new IC-7610. The difference between putting the QSO in the log or trying another time is the capability of your receiver. The high-performance RMDR in the IC-7610 can pick out the faintest of signals even in the presence of stronger, adjacent signals. The IC-7610 introduces dual RF direct sampling receivers. Achieving 100dB RMDR, these receivers rival that of other top-of-the-line transceivers. The IC-7610 also comes with a high-speed, high-resolution, real-time spectrum scope on a 7-inch color display.

Description

Innovative RF Direct Sampling System

Introduced with the IC-7300, Icom’s RF Direct Sampling System has made SDR performance affordable. Direct Sampling means incoming RF signals are digitized by the Analog-to-Digital Converter and immediately processed by the FPGA (Field-Programmable Gate Array). This process greatly reduces distortion that naturally occurs in the various mixer stages found in traditional superhetrodyne receivers.

Astonishing 110 dB* RMDR

The RF Direct Sampling System in the IC-7610 is capable of 110 dB RMDR. This performance gives you the ability to pull weak signals out of the noise of strong adjacent signals. There is a difference you can actually hear as the desired signal comes out of the pileup!

Customized VCXO Is Used for the Master Clock

Reducing phase noise in a receiver is always a challenge as it is a natural characteristic of a receiver. The master clock of the IC-7610 utilizes a low phase noise VCXO (Voltage Controlled Crystal Oscillator), combined with Icom’s years of technical expertise to design a common power supply for the VCXO and FPGA, yielding an ultra-low phase noise. Also, a 10 MHz reference signal can be input to the IC-7610 for higher precision.

Independent Dual Receiver

Whether listening to both sides of a rare DX station running split, or looking for a multiplier on a different band or mode, the dual receivers in the IC-7610 have you covered. Two separate DIGI-SEL preselectors, two separate Band Pass Filter networks, feed two separate A/D converters into the FPGA.

DIGI-SEL for Main and Sub Bands

The DIGI-SEL preselectors are RF filters with sharp, narrow passband characteristics preventing Analog-to-Digital Converter overflow from large out-of-band signals when sampling the RF signals. Additionally the third and higher order IMD components are reduced. This is ideal when strong signals are received in a contest pile-up or from broadcast stations on adjacent frequencies or bands.

Built-in Automatic Antenna Tuner

The built-in automatic antenna tuner memorizes its settings based on your transmit frequency, so that it can recall the tuning setting when you switch operating bands. The emergency tuner function* enables you to operate for short periods of time with an antenna with a high SWR.

Dual Receivers, Dual Spectrum Scopes

The IC-7610 provides dual reception, on different bands, as does the high-speed, high-resolution spectrum scopes. Whether watching for a band opening, working a rare DX station operating split, or searching for a multiplier, the ability to watch each receiver separately allows the operator to concentrate on pulling in a weak signal. The scopes provide class-leading performance in resolution, sweep speed and a 100 dB dynamic range. Scroll mode automatically keeps the operating signal within the scope range. To navigate around the band easier, connect a PC mouse to the USB port for point and click tuning of the receivers.
