MICROWAVE CORPORATION HMC429LP4 v01.0604 MMIC VCO w/ BUFFER AMPLIFIER, 4.45 - 5.0 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifier for: Pout: +4.0 dBm • 802.11a, HiperLAN WLAN Phase Noise: -105 dBc/Hz @100 KHz • VSAT, UNII & Microwave Radio No External Resonator Needed • Test Equipment & Industrial Controls Single Supply: 3V @ 30 mA • Military QFN Leadless SMT Package, 16 mm2 Functional Diagram General Description The HMC429LP4 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO with integrated resonator, negative resistance device, varactor diode, and buffer amplifier. Covering 4.45 to 5.0 GHz, the VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 4.0 dBm typical from a single supply of 3.0V @ 30mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package.
