RFVC1837
11.1GHz to 12.5GHz MMIC VCO with
Fo/2 and Fo/4 Outputs
RFMD's RFVC1837 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 11.1GHz to 12.5GHz its monolithic structure
provides excellent temperature, shock, and vibration performance.
Output power (Fo) is +8dBm 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 265mA which can be
further reduced to 205mA by disabling the divider functions if not
required. The RFVC1837 is available in a low cost 5mm x 5mm surface
mount plastic overmolded QFN outline.
