HMC505LP4 / 505LP4E v01.0805 MMIC VCO w/ BUFFER AMPLIFIER, 6.8 - 7.4 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifier for: Pout: +11dBm • VSAT & Microwave Radio Phase Noise: -106 dBc/Hz @100 kHz • Test Equipment & Industrial Controls No External Resonator Needed • Military Single Supply: +3V @ 80 mA QFN Leadless SMT Package, 16mm2 Functional Diagram General Description The HMC505LP4 & HMC505LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 6.8 to 7.4 GHz, the VCO’s phase noise performance is excellent over temperature, shock and vibration due to the oscillator’s monolithic structure. Power output is +11 dBm typical from a single supply of +3V @ 80 mA. The voltage controlled oscillator is packaged in a leadless QFN 4x4 mm surface mount package.
