MAX2209AEBS+T10

19-5493; Rev 0; 9/10 TION KIT EVALUA BLE IL AVA A RF Power Detector with Shutdown Control 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 Q0.5dB relative to room temperature. Features S -25dBm to -5dBm Power Detection Range S ±0.5dB Detection Error Due to Temperature S +2.7V to +5V Single-Supply Operation S Space-Saving 4-Bump, 1mm2 UCSP Package S Shutdown Control S 140ns Step-Response Time The MAX2209A comes in a space-saving 2 x 2, 0.5mm pitch UCSP™.

The device is ideal for wideband code-division multiple access (WCDMA), cdma2000M, and high-speed downlink/uplink packet access. The MAX2209A accepts an RF signal at the input, and outputs a temperature-independent voltage related to the input signal power. The output voltage expressed in dBV is proportional to the input power expressed in dBm. The device has a detection range from -25dBm to 0dBm. PA SMA TEST POINT 7.5kI Applications Information The typical application circuit, as taken from the MAX2209A EV Kit, is shown in Figure 1. The IC can be shut down by forcing the RFIN/SHDN DC voltage low through a 2kω resistor. The output of the detector goes to an ADC for further processing by the baseband system. Connect a series resistor and shunt capacitor to the MAX2209A output to reduce residual amplitude ripple. The series resistor should not be less than 1kI. ADC MAX2209A There are two areas that require attention: the GND pin and the supply bypassing. Connect the GND pin to the PCB ground with a GND via as close as possible, and bypass VCC to ground with a capacitor as close as possible to the part.
