RFVC1844
10.8GHz to 12.1GHz MMIC VCO with
Fo/2 and Fo/4 Outputs
RFMD's RFVC1844 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 10.8GHz to 12.1GHz 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 -113dBc/Hz at 100kHz offset. The device operates from a
low supply current of 280mA which can be further reduced to 220mA by
disabling the divider functions if not required. The RFVC1844 is available in
a low cost 5mm x 5mm surface mount plastic overmolded QFN outline.
