ECM014 Operating Principles Features ECM014 6x6mm size Power Amplifier Module (PAM) cellular band CDMA (digital) AMPS (analog) handset market. utilizes InGaP technology multi layer laminate base, over molded modular package with signal pad. offers Reliability Quality EiCs proprietary InGaP provides excellent reliability used infrastructure industry. InGaP inherently superior AlGaAs HBT. surface defect density InGaP much lower than that AlGaAs. 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 robust performance superior conventional AlGaAs HBT. InGaP goes through product burn-in test well. large sample group, usually pieces, goes through burn-in test ambient temperature 1000 hours. number than calculated based upon data collected. MTTF simply 1/FIT, this MTTF should agree with life test results. agreement between MTTF from life test essential: validates both tests! there large discrepancy [2], quality claim flawed. Although handset applications have stringent operating requirements infrastructure market, high reliability InGaP offers assurance user high quality product designed high volume production. InGaP Patent-pending Circuit Design Offers Temperature Variation Current gain InGaP varies about over +85oC range, compared with AlGaAs HBT. This gain variation over temperature, coupled with patent-pending circuit design approach, provides more stable electrical performance. III. ECM014 Offers High Gain Margin Transmitter Chain Design typical gain ECM014 27dB. This high gain allows driver amplifier very linear which results reduced current. Taking into account loss front PAM, driver needs deliver only 4dBm linear power. P1dB driver amplifier should more than 10dBm.

lower gain used, driver needs provide more power, expense more operation current possible degradation ACPR. Therefore ECM014 replace lower gain PAM, this allows driver work lower output power provide better ACPR, this improved performance offers more design margin transmitter chain. Easy Shut Down Leakage Current connected directly battery, therefore shut down required. voltage applied Vref pin, which then brings quiescent current. control switches quiescent current 50mA output power range. power range below 16dBm; high power range from 16dBm full power.
Removing voltage applied Vref pin, quiescent current will drop small leakage current, typically <10uA. leakage current allows longer standby time phone. General Application requires minimal number external components. Both input output dc-blocked within shown function diagram. input connected ground through shunt inductor within PAM. ECM014 designed with quiescent current 50mA typical power mode. full CDMA power 28dBm, operation current will greater than 500mA. Therefore "quasi class "deep class amplifier. operation current increases with output power. CDMA signal time varying amplitude. peak power above average power more accurately defined PDF, power density function). peak power clipped amplifier saturation power level, distortion signal will cause ACPR deteriorate rapidly. Therefore P1dB tested SINE wave) amplifier should over 31dBm provide good ACPR output power. 100pF capacitor required adjacent Vcc2 pin. addition, large capacitor (>uF) required. CDMA signal time-varying amplitude; therefore draws operation current corresponding instantaneous demand power. large capacitor near-by electric charge reservoir, providing current demand. long electrical path from battery behaves large inductor; instantaneous demand current will cause voltage drop, resulting poor ACPR. evaluation board, large shunt capacitor added protect Vref from power supply over-voltage during ON/OFF. This similar different from ESD. Therefore rise fall time test power down feature needs tested with shunt capacitor Vref removed.
