ECM168_05

ECM168 Product Features • 1.9 GHz Power Amp Module • +34 dBm Linear Output Power • 33.5 dB Gain • Single +10V Supply • No negative voltage required • Low cost metal package • MTTF > 100 Years The Communications Edge TM Product Information PHS +34 dBm 10V Module Product Description The ECM168 is a high performance PAS Amplifier Module offering excellent linearity. The internally matched multi-stage amplifier has 33.5 dB gain while achieving +34 dBm linear output power to meet PHS’s stringent ACLR requirements. The ECM168 uses a high reliability InGaP/GaAs HBT process technology and does not require any external matching components. The module has an added benefit by not require any negative biasing voltages; an internal active bias allows the ECM168 to maintain high linearity over temperature and operate directly off a single +10V supply. A low-cost metal housing allows the device to have a low thermal resistance and achieves over 100 years MTTF. All devices are 100% RF and DC tested. The ECM168 is targeted for use as a driver amplifier in wireless infrastructure where high linearity and high power is required. This combination makes the device an excellent candidate for next generation PAS base stations.

Please note that for reliable operation, the evaluation board will have to be mounted to a much larger heat sink during operation and in laboratory environments to dissipate the power consumed by the device. The use of a convection fan is also recommended in laboratory environments. 2. The area around the module underneath the PCB should not contain any soldermask in order to maintain good RF grounding.
