A breakthrough product, ULN-8R is an 8-frequency, 80MHz to 120MHz Frequency Reference for Radar Applications. ULN-8R has up to 8 different low-g sensitivity crystal frequencies built-in that can be selected via a 3-pin TTL interface for in-situ channel selection. ULN-8R is designed to work as a selectable low phase-noise frequency reference for Radar Applications, SatCom,broadcast, and test and measurement equipment.
At only 3 x 2.5 x 0.7 inches small, ULN-8R is tested against shock to MIL-STD-202G, M213 Condition C, and against vibration to MIL-STD-202G, M204 Condition C, and ages at less than 1ppm per year. ULN-8R has an extended temperature range operation and can operate from +9V to +18V at less than 0.7W power consumption. ULN-8R is available with 8 custom frequencies, or select from off-the-shelf frequency ranges such as 106MHz to 109MHz.
Typical phase noise performance of the ULN-8R with a 107MHz carrier is -104dBc/Hz at 10Hz, – 131dBc/Hz at 100Hz, -152dBc/Hz at 1KHz, -160dBc/Hz at 10KHz, and -168dBc/Hz at 1MHz.
