RFVC1821
Low Noise MMIC VCO with Buffer Amplifier
4.45GHz to 5.2GHz
RFMD’s RFVC1821 is a 3V InGaP MMIC VCO with an
integrated buffer amplifier operating over a frequency range
of 4.45GHz to 5.2GHz. Its monolithic tuning structure provides
excellent temperature, shock, and vibration performance while
its integrated buffer amplifier provides an output power of
+8dBm from a 3V supply. Phase noise is -108dBc/Hz at
100kHz offset. The RFVC1821 is available in a low cost
leadless ceramic 4mm x 4mm surface mount QFN outline.
