The MAX2209A is a wideband (800MHz to 2GHz) RF power detector. It takes an RF signal from the directional coupler at the input, and outputs a DC voltage proportional to the RF peak voltage. The change in output voltage versus temperature is very repeatable from part to part and enables a lookup table based on nominal behavior, minimizing the effective detection error to less than ±0.5dB relative to room temperature.
The MAX2209A comes in a space-saving 2 x 2, 0.5mm pitch UCSP™.
Applications
- Dual-Band WCDMA Handsets
- High-Speed Downlink Packet Access (HSDPA)
- High-Speed Uplink Packet Access (HSUPA)
