KOSS-11 Communication radio-receiving device


Functional features:

  • the communication radio-receiving device is intended for reception of the microwave oven of digital radio signals of the range of
    1 - 40 GHz;

  • the device is issued in basic and expanded executions. In expanded execution the device is completed with a set of replaceable modules of low-noise converters and the FM and AM built-in demodulator of signals (with a bandwidth of the demodulated signals to 37,5 MHz).

Technical features:

  • range of working frequencies in the basic embodiment of 1 - 2,7 GHz, in the expanded embodiment of 1 - 40 GHz;
  • the noise ratio isn't worse than 1 dB;
  • transfer rate not less than 100 dB with possibility of manual adjustment in the range not less minus 30 dB;
  • frequency of output signals of intermediate frequency (140 ± 20) MHz;
  • attenuation of level of combinational components of the 3rd order not less than 30 dB;
  • image attenuation not less than 60 dB;
  • bandwidth on the output intermediate frequency (in the expanded embodiment): 0,5; 1,1; 2,2; 2,7; 3,2; 4,0; 6,0; 12,0; 22,0; 31,0 and 37,5 MHz;
  • variation group-delay time in the band of 40 MHz not more than 10 nsec;
  • the level of attenuation of phase noises in the band of 1 Hz at least 80 and 90 dB at offset 1 and 10 kHz, respectively;
  • control panel or via RS-232C from PC;
  • alphanumeric LCD display;
  • storing up to 10 settings when powered off;
  • automatic initialization the current setting after shutdown or power failure;
  • real-time clock;
  • automatic program-temporary changes the settings (if necessary).

Conditions:

  • supply voltage (94 ... 255) V, (48 ... 62) Hz;
  • operating temperature range +5°C ... +40°C;
  • overall dimensions 300 x 105 x 315 mm;
  • weighs less than 6 kg in the basic embodiment.
