RFVC1839A
12.44GHz to 13.76GHz MMIC VCO with Fo/2 and Fo/4 Outputs
RFMD's RFVC1839A 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 12.44GHz to 13.76GHz 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. Max Phase noise is -108dBc/Hz at 100kHz offset. The device operates from a low supply current of 270mA which can be further reduced to 210mA by disabling the divider functions if not required. The RFVC1839A is available in a low cost 5mm x 5mm surface mount plastic overmolded QFN outline.
