Narrowband sources
High Performance Radar Exciters
I2R Electronics manufactures a series of narrowband tunable sources compliant with MIL-STD 883 and rated for ingress protection level 67. Targeted for high resolution S, C and X band Doppler weather RADAR these sources offer coherency over 10Hz to 1MHz integration bandwidth of -64dBc at C band. Automated spurious test at 1MHz frequency step guarantees a maximum spurious of -60dBc at all frequency settings over operational bandwidths to 250MHz. DDS based control enables frequency switching speeds of below 200ns and in combination with the on board processor allow user defined source modulation. Use of low g-sensitivity 0.3ppb/g oven controlled crystal internal reference ensures close in phase noise below -70dBc/Hz at 10Hz and operational temperature ranges from -40°C to +85°C . The robust high reliability design based around I2R's proprietary HMIC process make the narrowband tunable sources the right choice for high specification, harsh environment marine or terrestrial deployments.
Special Features:
- High coherency -64dBc at C band
- Low phase noise -124dBc/Hz at 100KHz at 5.65GHz
- Fast DDS based frequency switching < 200ns
- Low spurious below -60dBc with 100%automated spurious test.
- Wide operational temperature range -40°C to +85°C
- Weather resistant seal : IP67.
