MAX2205–MAX2208
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.
The MAX2206 features 40dB dynamic range, making it ideally suited to GSM/EDGE applications.
The MAX2207 offers reduced current consumption for TDMA applications.
The MAX2205/MAX2208 each have an integrated filter to allow for average power detection of CDMA signals over a 25dB dynamic range.
The MAX2206/MAX2207/MAX2208 offer internal 50Ω termination for interfacing with a directional coupler.
The MAX2205 has a high-impedance input to provide a lowloss resistive tap in CDMA applications.
All devices allow the user to control the averaging time constant externally.
The MAX2205–MAX2208 come in a space-saving 2 ✕ 2, 0.
5mm-pitch UCSP™ and require only three external components.
