RF Power Detectors in UCSP
General Description Features
Space-Saving 2 2 UCSP Occupies Only 1mm2 Internal Temperature Compensation Gives 0.3dB Detection Accuracy No External Filter or Op Amp Required Power-Detection Range 40dB (MAX2206) 25dB (MAX2205/MAX2207/2208)

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 50 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 th
e user to control the averaging time constant externally. The MAX2205 MAX2208 come in a space-saving 2 2, 0.5mm-pitch UCSPTM and require only three external components.
