DESCRIPTION
The ACD0900 MMIC is a high performance downconverter
fabricated entirely in GaAs. It is designed for use as the 2
nd
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
TCKT
: Maximum voltage that may be applied to pin 11 of the
device without damaging the IC. DC blocking capacitor (1500pF)
between pin11 and the external tuning circuit is mandatory.
