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.

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Note:
(1) V
TCKT
: Maximum voltage that may be applied to pin 11 of the device without
damaging the IC. DC blocking capacitor (1500 pF) between pin 11 and the
external tuning circuit is mandatory.
Stresses in excess of the absolute ratings may cause permanent
damage. Functional operation is not implied under these conditions.
Exposure to absolute ratings for extended periods of time may
adversely affect reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.
