- Buyers Guide
Hittite Microwave Corp., a supplier of complete MMIC-based solutions for communication and 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 that 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 -40° to +85°C with a frequency drift of only 2 ppm/°C. The Vtune port of the HMC-C200 accepts an analog tuning voltage from +5 to +12 V, 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 +15 V 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.
