RFVC1838 11.57GHz to 12.70GHz MMIC VCO with Fo/2 and Fo/4 Outputs RFMD's RFVC1838 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 11.57GHz to 12.70GHz 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 lo
