RFVC1837

11.1GHz to 12.5GHz MMIC VCO with

Fo/2 and Fo/4 Outputs

RFMD's RFVC1837 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 11.1GHz to 12.5GHz its monolithic structure

provides excellent temperature, shock, and vibration performance.

Output power (Fo) is +8dBm and is flat across the tuning voltage range

of 1.5V to 14.5V. Phase noise is typically -113dBc/Hz at 100kHz offset.

The device operates from a low supply current of 265mA which can be

further reduced to 205mA by disabling the divider functions if not

required. The RFVC1837 is available in a low cost 5mm x 5mm surface

mount plastic overmolded QFN outline.
