BROADBAND HIGH OIP3 AMPLIFIER
High Linearity Amplifier Series Introduction EiC's High Linearity Amplifier family made series high reliability Amplifiers with high linearity. They matched specific frequency band application from 50MHz 3GHz. output P1dB from 24dBm. versions. OIP3 typically 40dBm
They packaged SOT89 package thermal dissipation. parts were designed with thermal resistance provide junction temperatures long lifetimes. Unlike Darlington amplifier family, high linearity family maintains high OIP3 over usable frequency range while requiring external matching circuits good various frequency bands (see datasheet details each commonly used frequency band), parts with temperature compensation, bias line temperature stabilizing resistor needed. InGaP offers Reliability Quality proprietary InGaP provides excellent reliability used infrastructure industry. InGaP inherently superior AlGaAs HBT. surface defect density InGaP much lower than AlGaAs.

However, InGaP HBTs equal. life test InGaP gone through 315oC junction temperature 50kA/cm2 over 6000 hours months), translating multi-million hours lifetime longer operation envelope [1]. This kind life test superior conventional AlGaAs HBT, many other reported InGaP HBT. InGaP product would through product burn-in test well. large sample group, usually pieces, goes through burn-in test ambient temperature 1000 hours. calculated based number failed devices, activation energy, etc. MTTF simply 1/FIT. This MTTF should agree with life test result when dominant failure mechanism (not other components like resistor, inductor, capacitor, etc). This shown Fig. agreement between MTTF from life test essential: validates both tests. there large discrepancy [2], quality claim flawed. Figure describes scenario. When short life test result high activation energy derived, really long operation time mistakenly claimed when another activation energy mechanism identified. Careful Thermal Design High Linearity Amplifier Although High Linearity Amplifier series only offers medium power level (<25dBm), thermal design still factor affecting reliability. Even power amplifier, cells closely spaced die, transistor junction temperature still high, negatively affecting reliability. Utilizing EiC's experience Power Amplifiers, each high linearity Amplifier carefully designed laid provide thermal resistance. ballasting also carefully crafted, which must bipolar transistor BJT, SiGe BJT, AlGaAs/GaAs HBT, InGaP/GaAs HBT, family substrate). III. High Linearity known high linearity [3]. Applying this feature High Linearity Amplifier, high OIP3 amplifier made. Compared with other transistor technology, InGaP easy process control which allows OIP3 maintained volume production. Broad Operation Frequency Range

high linearity amplifier family requires external matching components achieve good matching. They matched commonly used application 3GHz. datasheet covers recommended matching circuits each frequency band. expensive high-Q capacitors used keep cost minimal. Since external matching circuit required, grounding inductance also requires attention. high grounding inductance layout could cause gain reduction. recommended layout datasheet. Multiple holes recommended both electrical grounding inductance thermal resistance. amplifier biased through inductor choke. User choose value each application frequency band. choke inductor needs able accommodate bias current. blocking capacitors both input output required well. Temperature Stabilization bipolar transistors have negative temperature coefficient Vbe(temperature). BJT, about -2mV/oC, GaAs -1mV/oC. result, curve circuit will shift lower voltage temperature rises. This more severe circuit with twice large temperature coefficient. EC1089 ECG009 high linearity amplifier family have built temperature compensation circuit. They biased from supply directly without using temperature stabilizing resistor between power supply choke. ECG014 ECG015 have temperature compensation built inside Although they operate from power supply, temperature variation exceed application limit. temperature stabilizing resistor inserted between power supply choke reduce performance variation over temperature bias current change. However temperature stabilizing resistor means power supply voltage higher than Conclusion EiC's InGaP High Linearity Amplifier Series offer high linearity, good gain, high reliability. Careful thermal design assures cool operation temperature. Crosscheck between product burn-in transistor life test result validates both tests. This series products will best serve infrastructure market. Reference
