HMC430LP4 / 430LP4E v06.1106 MMIC VCO w/ BUFFER AMPLIFIER, 5.0 - 5.5 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifier for C-Band applications such as: Pout: +2 dBm • 802.11a & HiperLAN WLAN No External Resonator Needed • VSAT Radios Single Supply: 3V @ 27 mA • UNII & Point-to-Point Radios 16mm2 Leadless SMT Package Functional Diagram General Description Phase Noise: -103 dBc/Hz @100 kHz The HMC430LP4 & HMC430LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. The VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 2 dBm typical from a 3V supply voltage. The voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package. VCOS & PLOs - SMT 11 Electrical Specifi cations, TA = +25° C, Vcc = +3V Parameter Min.
