  • 1.9 GHz Power Amp Module
  • +34 dBm Linear Output Power
  • 33 dB Gain
  • Single +10V Supply
  • No negative voltage required
  • Low cost metal package
  • MTTF > 100 Years

Applications

  • PAS Base Stations
  • Repeaters 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 requirements of better than -65 dBc ACLR at a ±600 kHz offset from the carrier. The ECM168 uses a high reliability InGaP/GaAs HBT process technology and does not require any external matching components. The m odule has an added benefit by not require any negative biasing voltages; an internal active bias allows the ECM 168 to maintain high linearity over temperature and operate directly off a single +10V supply. A low-cost metal hous ing allows the device to have a low thermal resist ance and achieves over 100 years MTTF. All devices are 100% RF and DC tested. The ECM168 is targeted for us e as a driver amplifier in wireless infrastructure wher e high linearity and high power is required. This combination makes the device an excellent candidate for next generation PAS base stations. Functional Diagram Top View Pin No. Function

The use of a convection fan is also recommended in laboratory environments. Performance Graphs Gain vs. Channel Power
