DESCRIPTION
The ACD0900 MMIC is a high performance downconverter fabricated entirely in GaAs. It is designed for use as the 2nd 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. *VTCKT : 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. ABSOLUTE MAXIMUM RATINGS ACD0900S3C S3C
