RFVC1842

9.3GHz to 10.7GHz MMIC VCO with

Fo/2 and Fo/4 Outputs

RFMD's RFVC1842 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 9.3GHz to 10.7GHz 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 -115dBc/Hz at 100kHz offset. The device operates from a

low supply current of 275mA which can be further reduced to 215mA by

disabling the divider functions if not required. The RFVC1842 is available in

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