IQD Frequency Products, a subsidiary of the Würth Elektronik, has updated the IQRB-3 low noise rubidium oscillator. It is currently focusing its engineering expertise on providing best-in-class rubidium atomic clock oscillators. Following the recent releases of new products in this portfolio, the ICPT-1 and the IQRB-4, and an extensive update on the IQRB-1, IQD is now able to share new data on the IQRB-3.
The IQRB-3 can be synchronized to a 1 PPS signal as well as used as a 1 PPS source. Additionally, it offers excellent phase noise performance of -110 dBc/Hz @ 1 Hz and a noise floor as low as -158 dBc/Hz. Furthermore, it combines a tight tolerance and ±0.3 ppb temperature stability (-20 to 60 °C) with great short term and long term stability. This makes the IQRB-3 an ideal fit for timing applications that require a very precise frequency.
As with all their high-end products, IQD recognizes that measurements given on the datasheet are specific to the test setup and environment, so they have compiled a handbook documenting the precise details for each line on the datasheet. If these don’t match your environment, they are happy to adapt and repeat the measurements as per requirements. Click here to download the handbook.
