WIDEBAND MMIC VCO WITH BUFFER
AMPLIFIER, 8GHz to 12GHz
Package: 4mmx4mmx1.1mm
Product Description
Features
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 single +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.
