General Description
The MAX2205–MAX2208 wideband (800MHz to 2GHz) power detectors are ideal for GSM/EDGE (MAX2206), TDMA (MAX2207), and CDMA (MAX2205/MAX2208) applications. The MAX2206/MAX2207/MAX2208 take an RF signal from a directional coupler at the input, and output a highly repeatable voltage. The output voltage increases monotonically with increasing input power. The output is compensated for temperature and process shifts, reducing the worst-case variation to less than ±1dB at full power and ±2.5dB at the lowest power.
