RFVC1839A

12.44GHz to 13.76GHz MMIC VCO with

Fo/2 and Fo/4 Outputs

RFMD's RFVC1839A 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 12.44GHz to 13.76GHz 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.

Max Phase noise is -108dBc/Hz at 100kHz offset. The device operates from

a low supply current of 270mA which can be further reduced to 210mA by

disabling the divider functions if not required. The RFVC1839A is available

in a low cost 5mm x 5mm surface mount plastic overmolded QFN outline.
