PRODUCT DESCRIPTION
The ACD0900 MMIC is a high performance
downconverter fabricated entirely in GaAs. It is
designed for use as the second 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 modified 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.
