Key Features
- High Linearity: Designed to meet high linearity requirements, making it suitable for applications in cable TV infrastructure and wireless infrastructure.
- High Signal Level Handling: Capable of handling high IF input signal levels with excellent performance.
- Flexible LO Configuration: The LO buffer can be driven differentially or single-ended, eliminating the need for a balun in some configurations.
- Internal Biasing: LO pins are internally biased to about 1.4V, requiring DC isolation from the external LO signal source.
- Wide Operating Frequency Range: Can operate with LO frequencies from 0.4GHz to 2.7GHz and IF input frequencies from 10MHz to 300MHz.
- Low Power Consumption: Low enable input current of 1µA when EN is high.
- Fast Enable/Disable Times: Turn on and turn off times are based on rise and fall times of the RF output envelope from full power to –40dBm.
Applications
- Cable TV Infrastructure: Downstream transmitters requiring high linearity and signal integrity.
- Wireless Infrastructure: Base stations and other wireless communication systems needing high performance upconverting mixers.
- RF and Microwave Systems: General use in RF and microwave systems where high signal level handling and linearity are crucial.
