IQD—a Würth Elektronik eiSos Group company— is pleased to announce completion of its extended rubidium portfolio with the comprehensive IQRB-2 rubidium oscillator handbook, summarising tests undertaken: from temperature stability and short-term stability to supply pushing and more.

The IQRB-2 fills the gap between the IQRB-1 and the IQRB-3; the IQRB-1 delivers a superb price performance ratio, whereas the IQRB-3 offers an exceptional phase noise performance paired with a 1 PPS synchronization. The IQRB-2 offers a superb phase noise close to the IQRB-3 performance: a close in phase noise of -108 dBc/Hz @ 1 Hz and a noise floor of -158 dBc/Hz @ 10 kHz and below. Although it does not offer a 1 PPS synchronisation, it is available at a more competitive price vs. the IQRB-3. With a short term stability of 0.0075 ppb @ Tau = 100 s and an aging performance of a maximum of 0.05 ppb per month, the IQRB-2 is still a perfect match for various time and frequency synchronization applications.
