hmc-cHittite launches industry leading commercial DRO product line. Targets X-band applications with -124 dBc/Hz phase noise at 10 KHz offset.

  Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced its first high performance dielectric resonator oscillator (DRO). An exciting new product, the HMC-C200 is one of the lowest phase noise X-band DRO products in the industry.

The HMC-C200 DRO features a customizable tuning frequency from 8.0 to 8.3 GHz, with -124 dBc/Hz SSB phase noise at 10 kHz offset, which makes the device ideal for a wide range of industrial, medical, military, test and measurement markets that require enhanced phase noise performance. The HMC-C200 features an internal voltage regulator which provides excellent frequency pushing performance of 5 kHz/V, while the output buffer delivers +14.5 dBm of output power and excellent frequency pulling performance into a 2.0:1 VSWR (5 kHz pp).

This DRO also satisfies the stringent system performance requirements of SDH/SONET communications, digital radio, Cable TV link, and satellite communications end-markets, which require very stable reference frequencies with low thermal drift. Internal temperature compensation allows the HMC-C200 to operate over a temperature range of -40ºC to +85ºC with a frequency drift of only 2 ppm/°C. The Vtune port of the HMC-C200 accepts an analog tuning voltage from +5V to +12V, and provides a range of ±1 MHz from the center frequency. Each DRO is tuned to order with a ±1 MHz offset from the specified center frequency.

Operating from a +6 to +15V single supply, the HMC-C200 is housed in a miniature 1.5” x 1.5” (36 x 36 mm) connectorized module that is moisture sealed, and features a field replaceable SMA connector.

HMC-C200 DRO is built to order, and the center frequency is specified at the time of purchase. For detailed ordering instructions please consult Hittite’s website.
