Double conversion superheterodyne<\/strong>
\nIcom’s basic idea about the best receiver circuit is to reproduce high fidelity audio without internal distortion. Our answer to achieve this goal is to adopt a double conversion superheterodyne system*. The double conversion system simplifies the electronic circuitry and reduces the number of components which cause internal distortion. The digital signal processing (DSP) technologies and image rejection mixer make it possible to adopt this system.
\n* A triple conversion system is used for the 1200MHz band.<\/em><\/p>\n

Independent dual receivers<\/strong>
\nAs seen in the above figure, the IC-9100 has 3 independent receiver circuits from the antenna connector to the second IF mixer (image rejection mixer). One each for HF\/50MHz, 144MHz, 430\/440MHz bands. See the table below for simultaneous receive pairs.<\/p>\n

\"\"<\/p>\n

32-bit floating point DSP & 24-bit AD\/DA converters<\/strong>
\nThe heart of the IC-9100 is the proven combination of the 32-bit floating point DSP and 24-bit AD\/DA converters. This powerful combination supports many digital processing features.<\/p>\n

\"\"<\/p>\n

AGC loop management<\/strong>
\nDigital IF filters, manual notch filter and other digital functions are incorporated in the AGC loop management controlled by the DSP unit. The AGC effectively works for the desired signal and rejects blocking by strong adjacent signals out of the filter passband. The AGC time constant presets (slow, medium and fast) give the flexibility and speed needed for working pile-ups.<\/p>\n

\"\"<\/p>\n

Digital IF filter<\/strong>
\nThe IC-9100 DSP allows you to \u201cbuild your own\u201d digital IF filter. You can quickly choose bandwidth, shape factor, and center frequency, so that you can work that rare DX station. Three filter memories allow you to change filter settings instantly, a great help during contesting or other tough conditions.<\/p>\n

\"\"<\/p>\n

Digital twin PBT and IF shift<\/strong>
\nAfter \u201cbuilding your own\u201d digital IF filter, you can use the digital twin Passband Tuning (PBT) to shift and narrow the IF passband until the interference is gone and you can clearly hear that weak signal.<\/p>\n

\"\"<\/p>\n

Noise reduction<\/strong>
\nThe 16-step variable noise reduction can significantly enhance the receiver’s signal-to-noise ratio, giving you a clean, clear audio signal that may make the difference between making the contact or not.<\/p>\n

Noise blanker<\/strong>
\nThe digital noise blanker reduces interference from pulse-type noise such as engine ignition. The noise blanker allows you to change the threshold level as well as blank duration parameter and attenuation level.<\/p>\n

RF speech compressor<\/strong>
\nThe digital RF speech compressor boosts average talk power, improving signal strength and readability in SSB mode. It is useful for for breaking through the noise and complete the QSO.<\/p>\n

Adjustable transmit bandwidth<\/strong>
\nThe transmit bandwidth is selectable from 100, 200, 300, 500Hz at the low-pass edge, and 2500, 2700, 2800, 2900Hz at the high-pass edge, respectively. Three types of high and low combinations can be stored in the memory as favorite settings.<\/p>\n

HF\/50MHz, 144MHz 100W, 430\/440MHz 75W<\/strong>
\nThe IC-9100 uses high efficiency power amplifiers and large heat sink providing stable output power, even during long periods of operation.<\/p>\n

+30dBm class third-order intercept point<\/strong>
\nDynamic range characteristicsUsing receiver design techniques introduced in Icom\u2019s highest grade HF transceivers, the IC-9100 has an IP3 of +30dBm (typ.) in 14MHz band. Even a weak signal adjacent to st rong signals is clear ly received by the IC-9100.<\/p>\n

\"\"<\/p>\n

Three first IF filters (3\/6\/15kHz) for HF\/50MHz band<\/strong>
\nThe IC-9100 comes with a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz FL-431 and 6kHz FL-430). By changing the first IF filter width according to the operating mode, the desired signal is protected from adjacent inband signals at the later stages for better receiver performance.<\/p>\n

\"\"<\/p>\n

RTTY demodulator and decoder<\/strong>
\nThe built-in RTTY demodulator and decoder allow you to instantly read an RTTY message on the display. No external units or PC required. The built-in tuning indicator visually helps in critical tuning.<\/p>\n

Ample CW functions<\/strong>
\nAll of the following CW capabilities are included in the IC-9100:<\/p>\n
