OR:  

The BGA7204 MMIC is an extremely linear Variable Gain Amplifier (VGA), operating from 0.4 GHz to 2.75 GHz. At minimum attenuation it has a gain of 18.5 dB, an output IP3 of 38 dBm and a noise figure of 7 dB. The attenuation range is 31.5 dB with an attenuation step of 0.5 dB. The gain control is offered through a digital parallel interface or a digital serial interface (SPI). The digital serial interface offers advanced features like reprogramming the attenuation curve and on-chip temperature monitoring. The interfaces can be combined to support response to fast fading. The serial interface can be used to pre-set the desired gain level, whereas the parallel interface can be used to select this gain setting in 0.15 μs.

Features and benefits

  • High output IP3 of 38 dBm
  • Attenuation range of 31.5 dB
  • Output power at 1 dB compression of 21 dBm
  • Noise figure of 7 dB at maximum gain
  • Single 5 V supply
  • Digital parallel and digital serial control (SPI)
  • Programmable attenuation curve
  • Temperature sensor
  • ESD protection on all pins (HBM > 2 kV)
  • Moisture sensitivity level 2
  • Compliant to Directive 2002/95/EC, regarding Restriction of Hazardous Substances

Applications

  • IF and RF applications
  • WiMAX and cellular base stations
  • Cable modem termination systems
  • Temperature compensation circuits
