RFVC1800

WIDEBAND MMIC VCO WITH BUFFER

AMPLIFIER, 8GHz to 12GHz

RFMD’s RFVC1800 wideband Voltage Controlled Oscillator is a GaAs InGaP HBT

MMIC with integrated VCO core and RF output buffer. The part operates from a sin-

gle +5V supply for circuit bias and 0 to +13V Vtune for frequency control. The

RFVC1800 is in an RoHS Compliant, compact QFN 4mmx4mm package that offers

low phase noise and low power consumption
