RFVC1843A RFVC1843A 10.19GHz to 11.33GHz MMIC VCO with Fo/2 and Fo/4 Outputs RFMD's RFVC1843A 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 10.19GHz to 11.33GHz its monolithic structure provides excellent temperature, shock, and vibration performance. Output power (Fo) is +7dBm and is flat across the tuning voltage range of 1.5V to 14.5V. Phase noise is typically -114dBc/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 RFVC1843A is available in a low cost 5mm x 5mm surface mount plastic overmolded QFN outline.
