Three Wide-band VCO Modules with Low Phase Noise
Tue, 04/17/2007 - 7:24am
Hittite Microwave Corporation introduces three wideband voltage controlled oscillator (VCO) modules which are suitable for test and measurement, military, microwave radio, space, industrial and laboratory applications from 4 to 12.5 GHz. The HMC-C028, HMC-C029 and HMC-C030 modules offer output frequency coverage from 4 to 8 GHz, 5 to 10 GHz, and 8 to 12.5 GHz respectively, and they feature an integrated buffer amplifier for increased output power and low frequency pulling characteristics. They exhibit SSB phase noise performance of -95 dBc/Hz at 100 kHz offset, and an output power of +21 dBm. Internal voltage regulation enables these fully integrated modules to operate from a single supply between +8 V and +15 V, while consuming less than 200 mA of current. The single-ended RF outputs are matched to 50 Ohms, while the Vtune ports accept analog tuning voltages from 0 to +13V, and can accommodate very fast tuning bandwidths. The HMC-C028, HMC-C029 and HMC-C030 share a common footprint, and are housed in hermetically sealed RoHS compliant modules which also meet stringent military and space solder material requirements.
