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.
