RFVC1849

12.9GHz to 14.1GHz MMIC VCO with

Fo/2 and Fo/4 Outputs

RFMD's RFVC1849 is a 5V InGaP MMIC VCO with an integrated frequency divider

providing additional Fo/2 and Fo/4 outputs. With an Fo frequency range of 12.9GHz

to 14.1GHz its monolithic structure provides excellent temperature, shock, and

vibration performance. Output power (Fo) is +7dBm and is flat across the tuning

voltage range of 1.5V to 14.5V. Phase noise is typically -109dBc/Hz at 100kHz

offset. The device operates from a low supply current of 260mA which can be

further reduced to 200mA by disabling the divider functions if not required. The

RFVC1849 is available in a low cost 5mm x 5mm surface mount plastic overmolded

QFN outline.
