HMC431LP4 / 431LP4E v04.1106 MMIC VCO w/ BUFFER AMPLIFIER, 5.5 - 6.1 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Ampl ifier Pout: +2 dBm for C-Band applications such as: Phase Noise: -102 dBc/Hz 100 kHz 802.11a & HiperLAN WLAN No External Resonator Needed VSAT Radios Single Supply: 3V 27 mA UNII & Point-to-Point Radios 2 16mm Leadless SMT Package Functional Diagram General Description The HMC431LP4 & HMC431LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance 11 devices, varactor diodes, and buffer ampl ifiers. The VCOs phase noise performance is excellent over temperature, shock, vibration and process due to the oscillators 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. Electrical Specifi cations, T = +25 C, Vcc = +3V A Parameter Min. Typ. Max.
