Key Features
- Doubly Balanced Mixer: Ensures low distortion and high port-to-port isolation.
- Low Distortion: Features a +24 dBm third-order intercept point (IP3) and a +10 dBm 1 dB compression point.
- Low LO Drive Required: Operates with a –10 dBm LO input.
- Wide Bandwidth: RF and LO input bandwidths up to 500 MHz and IF output bandwidth up to 200 MHz.
- Single- or Dual-Supply Operation: Allows for DC-coupled operation using dual supplies.
- No Insertion Loss: Unlike passive mixers, the AD831AP does not require an external diplexer or passive termination.
- Programmable Bias: Allows for a tradeoff between dynamic range and power consumption.
Applications
- High Performance RF/IF Mixer: Suitable for various RF and IF mixing applications.
- Direct to Baseband Conversion: Ideal for direct-coupled applications such as direct-to-baseband conversion and quadrature-amplitude demodulation.
- Image-Reject Mixers: Used in image-reject mixer configurations.
- I/Q Modulators and Demodulators: Applicable in I/Q modulation and demodulation circuits.
- Cellular and Two-Way Radio Base Stations: Can be used as a second mixer in these applications with reduced power consumption.
