RFVC1832 RFVC1832 7.9GHz to 8.8GHz MMIC VCO with Fo/2 and Fo/4 Outputs RFMD's RFVC1832 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 7.9GHz to 8.8GHz its monolithic structure provides excellent temperature, shock, and vibration performance. Output power (Fo) is +9dBm 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 240mA which can be further reduced to 180mA by disabling the divider functions if not required. The RFVC1832 is available in a low cost 5mm x 5mm surface mount plastic overmolded QFN outline.
