EVALUATION KIT AVAILABLE MAX9930MAX9933 2MHz to 1.6GHz 45dB RF-Detecting Controllers and RF Detector General Description Features The MAX9930MAX9933 low-cost, low-power logarithmic Complete RF-Detecting PA Controllers amplifiers are designed to control RF power amplifiers (MAX9930/MAX9931/MAX9932) (PA) and transimpedance amplifiers (TIA), and to detect Complete RF Detector (MAX9933) RF power levels. These devices are designed to operate Variety of Input Ranges in the 2MHz to 1.6GHz frequency range. A typical dynam- MAX9930/MAX9933: -58dBV to -13dBV ic range of 45dB makes this family of logarithmic ampli- (-45dBm to 0dBm for 50 Termination) fiers useful in a variety of wireless and GPON fiber video MAX9931: -48dBV to -3dBV applications such as transmitter power measurement, and (-35dBm to +10dBm for 50 Termination) RSSI for terminal devices. Logarithmic amplifiers provide MAX9932: -43dBV to +2dBV much wider measurement range and superior accuracy to (-30dBm to +15dBm for 50 Termination) controllers based on diode detectors. Excellent tempera- 2MHz to 1.6GHz Frequency Range ture stability is achieved over the full operating range of -40C to +85C.

The logarithmic amplifier is a Low Power: 17mW at 3V (typ) voltage-measuring device with a typical signal range of -58dBV to -13dBV for the MAX9930/MAX9933, -48dBV 13A (typ) Shutdown Current to -3dBV for the MAX9931, and -43dBV to +2dBV for the Available in a Small 8-Pin MAX Package MAX9932. The MAX9930MAX9933 require an external coupling Ordering Information capacitor in series with the RF input port. These devices PART TEMP RANGE PIN-PACKAGE feature a power-on delay when coming out of shutdown, MAX9930EUA+T -40C to +85C 8 MAX holding OUT low for approximately 2.5s to ensure glitch-free controller output. MAX9931EUA+T -40C to +85C 8 MAX The MAX9930MAX9933 family is available in an 8-pin MAX9932EUA+T -40C to +85C 8 MAX MAX package. These devices consume 7mA with a MAX9933EUA+T -40C to +85C 8 MAX 5V supply, and when powered down, the typical shut- MAX9933BGUA+T -40C to +105C 8 MAX down current is 13A. +Denotes a lead(Pb)-free/RoHS-compliant package.
