DESCRIPTION

TheACD0900 MMIC is a high performance downconverter

conversion stage in double-conversion tuners and cable

modems, downconverting 900 -1200 MHz RF inputs to a

fixed IF of 35 - 150 MHz (depending on LO frequency).

The IC incorporates a low noise amplifier, high linearity

double balanced mixer, phase splitter and oscillator in a

SOIC 16 lead surface mount package. The high degree of

functionality allows tuner manufactures to reduce size and

cost by lowering the component count and decreasing the

amount of production alignment steps, while significantly

improving performance and reliability.

*V

device without damaging the IC. DC blocking capacitor (1500pF)

between pin11 and the external tuning circuit is mandatory.
