RFVC1832A RFVC1832A 7.8GHz to 8.9GHz MMIC VCO WITH 7.8GHz TO 8.9GHz MMIC VCO WITH Fo/2 AND Fo/4 OUTPUTS Package: Plastic QFN, 32pin, 5mmx5mmx0.85mm Features Multiple Frequency Outputs No External Resonator Required Integrated Frequency Divider Phase Noise: -115dBc/Hz at 100kHz Offset Flat Output Power Over Frequency Tuning Range 1.5V to 14.5V Fo: 9dBm Fo/2: 5dBm Fo/4: -2dBm Functional Block Diagram Product Description Low Power Consumption Fo: 7.80GHz to 8.90GHz Fo/2: 3.90GHz to 4.40GHz Fo/4: 1.95GHz to 2.20GHz 5V/240mA (Divider On) 5V/180mA (Divider Off) 32-Lead 5mmx5mm Plastic Overmolded QFN Applications RFMD's RFVC1832A 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 7.8GHz to 8.9GHz 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 RFVC1832A is available in a low cost 5mmx5mm surface mount plastic overmolded QFN outline.
