Hittite MICrowave推出三款新型GaAs HBT MMIC壓控振蕩器(VCO)，適用于11、12和24GHz的點(diǎn)對點(diǎn)/多點(diǎn)、VSAT、調(diào)試設(shè)備和工業(yè)應(yīng)用。MMIC VCO面向微波無線電、工業(yè)、汽車及軍事應(yīng)用。

HMC513LP5、HMC514LP5和HMC533LP4是全集成的InGaP HBT VCO。這種MMIC VCO具有一個(gè)集成振蕩器、負(fù)阻抗器件和一個(gè)變?nèi)荻O管，由于采用單片結(jié)構(gòu)，在整個(gè)工作溫度范圍內(nèi)有極好的相位噪聲性能及抗震能力。這三款VCO輸出功率高，工作電壓為單一正極性電源，也可禁用預(yù)放大功能以降低功耗。HMC513LP5型10.43～11.46GHz HBT MMIC VCO和HMC514LP5型11.17～12.02GHz HBT MMIC VCO有+7dBm功率輸出和Fo/2、1/4輸出。兩種VCO都采用無引鉛的QFN 5×5mm表面封裝，工作電壓為單+3V電源，在100kHz偏置時(shí)，有-110dBc/Hz SSB相位噪聲。

HMC533LP4是一個(gè)23.8～24.8GHz MMIC VCO，輸出功率+12dBm，1/16輸出。HMC533LP4采用無鉛QFN 4×4mm表面封裝，工作電壓+5V，在100kHz偏置時(shí)，有-95dBc/Hz SSB相位噪聲。

The HMC513LP5(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC513LP5(E) integrates resonators, negative resistance devices, varactor diodes and feature half frequency and divide-by- 4 outputs. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is +7 dBm typical from a +3V supply voltage. The prescaler function can be disabLED to conserve current if not required. The voltage controlled oscillator is packaged in a leadless QFN 5x5 mm surface mount package, and requires no external matching components.
