RFVC1838A

12.1GHz to 13.15GHz MMIC VCO with

Fo/2 and Fo/4 Outputs

RFMD's RFVC1838A 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

12.1GHz to 13.15GHz 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 -112dBc/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

RFVC1838A is available in a low cost 5mm x 5mm surface mount plastic

overmolded QFN outline.
