HMC429LP4 / 429LP4E v02.0805 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 & HMC429LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. 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 4x4 mm surface mount package.
