Description :

The IC-7700 achieves first-class performance on HF/50 MHz bands. The transceiver use two 32-bit floating point DSP and a double conversion system with 2nd-stage image rejection mixer. Three roofing filter of 15kHz, 6kHz and 3kHz provides high blocking dynamic range. The transmitter's power amplifiers use a combination of push-pull final with two MRF150 transistors, having proven reliability in professional communications. These devices generate a stable 200 Watts of output power from HF to 54MHz. The radio has a built-in RTTY and PSK31 modulator/demodulator. By simply connecting a USB key-board, you can immediately start enjoying these modes. In addition, you can also pre-program transmit messages in the internal message memory or a USB memory stick and transmit them even without typing a message from a USB keyboard.

Advance receiver performance. The IP3 performance of a radio can be improved by sacrificing sensitivity, but ICOM considers this a poor choice. To achieve real high-performance, ICOM reviewed all of the analog receiver circuitry. The IC7700 employs mechanical relay BPF switching, a digitally tuned pre-selector, and three hi-spec 1st IF filters in a clean and simple double-conversion superheterodyne design. By balancing the analog and DSP functions, the IC-7700 provides superior sensitivity simultaneously with a superb dynamic range of 110dB, and +40dBm IP3 (even in USB mode with 2.4 kHz filter bandwidth). An IP2 point of more than +110dBm means the 2nd order distortion from strong broadcast stations will be completely eliminated. The endless pursuit of leading analog circuit engineering makes it possible to achieve this leading edge level of performance.
