1 FEATURES Integrated Monolithic Downconverter 8 db Noise Figure 0 db Conversion Gain High Linearity Small Size Low Cost High Reliability VHF/UHF CATV/TV Tuner Downconverter Data Sheet Rev. S3 Package Modified 6 Pin SOIC PRODUCT DESCRIPTION The MMIC is a high performance downconverter fabricated entirely in GaAs. It is designed for use as the second conversion stage in doubleconversion tuners and cable modems, downconverting MHz RF inputs to a fixed IF of 3 0 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 6 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.
