19-0859; Rev 0; 8/07 EVALUATION KIT AVAILABLE 2MHz to 1.6GHz 45dB RF-Detecting Controllers and RF Detector MAX9930­MAX9933 General Description Features The MAX9930­MAX9933 low-cost, low-power logarith- o Complete RF-Detecting PA Controllers mic amplifiers are designed to control RF power ampli- (MAX9930/MAX9931/MAX9932) fiers (PA) and transimpedance amplifiers (TIA), and to o detect RF power levels. These devices are designed to Complete RF Detector (MAX9933) operate in the 2MHz to 1.6GHz frequency range. A typi- o Variety of Input Ranges cal dynamic range of 45dB makes this family of logarith- MAX9930/MAX9933: -58dBV to -13dBV mic amplifiers useful in a variety of wireless and GPON (-45dBm to 0dBm for 50 Termination) fiber video applications such as transmitter power mea- MAX9931: -48dBV to -3dBV surement, and RSSI for terminal devices. Logarithmic (-35dBm to +10dBm for 50 Termination) amplifiers provide much wider measurement range and MAX9932: -43dBV to +2dBV superior accuracy to controllers based on diode detec- (-30dBm to +15dBm for 50 tors. Excellent temperature stability is achieved over the Termination) full operating range of -40°C to +85°C. o 2MHz to 1.6GHz Frequency Range The choice of three different input voltage ranges elimi- o Temperature Stable Linear-in-dB Response nates the need for external attenuators, thus simplifying o Fast Response: 70ns 10dB Step PA control-loop design. The logarithmic amplifier is avoltage-measuring device with a typical signal range of o 10mA Output Sourcing Capability -58dBV to -13dBV for the MAX9930/MAX9933, -48dBV o Low Power: 17mW at 3V (typ) to -3dBV for the MAX9931, and -43dBV to +2dBV forthe MAX9932. o 13µA (typ) Shutdown Current The MAX9930­MAX9933 require an external coupling o Available in a Small 8-Pin µMAX Package capacitor in series with the RF input port. These devicesfeature a power-on delay when coming out of shutdown,holding OUT low for approximately 2.5µs to ensure Ordering Information glitch-free controller output. The MAX9930­MAX9933 family is available in an 8-pin PIN- PKG PART TEMP RANGE µMAX® package. These devices consume 7mA with a
