Rubidium oscillator til de mest krævende applikationer

Ny rubidium oscillator fra IQD er velegnet til LTE basestationer, højhastigheds trådløs kommunikation samt overvågningsapplikationer (in english).

The electrical connections include an SMA connector for RF output, RS232 connectors RX & TX, a voltage control input and a frequency locked monitor. With a short term stability 100 times better than a typical Oven Controlled Crystal Oscillator (OCXO) at 0.002ppb/s at 100s, this model is ideal for frequency calibration, Long Term Evolution (LTE) base stations, high speed wireless communications and surveillance applications.

Based around an atomic clock, the IQRB-2 delivers an accuracy of ±0.3ppb irrespective of temperature fluctuations from -20 to 65°C and operates at a standard frequency of 10MHz with a Sinewave 50 ohm output. The ageing is ±0.05ppb per month and the IQRB-2 has a voltage control option to give a controllable frequency tuning of +/- 2ppb max.

The module is specified with a supply voltage of 12V, although the product will operate over a voltage range of 12V to 18V, with a power consumption of 6W when stabilised and a warm up time of typically 5 minutes. The device can be operated over a temperature range of -20 to +65 degrees C and Mean Time Between Failure (MTBF) is approximately 100,000 hours.
