19-2288; Rev 2; 12/07 2.5GHz 45dB RF-Detecting Controllers MAX4000/MAX4001/MAX4002 General Description Features The MAX4000/MAX4001/MAX4002 low-cost, low-power Complete RF-Detecting PA Controllers logarithmic amplifiers are designed to control RF power Variety of Input Ranges amplifiers (PA) operating in the 0.1GHz to 2.5GHz fre- MAX4000: -58dBV to -13dBV quency range. A typical dynamic range of 45dB makesthis family of log amps useful in a variety of wireless appli- (-45dBm to 0dBm in 50) cations including cellular handset PA control, transmitter MAX4001: -48dBV to -3dBV power measurement, and RSSI for terminal devices. (-35dBm to +10dBm in 50) Logarithmic amplifiers provide much wider measurement MAX4002: -43dBV to +2dBV range and superior accuracy to controllers based on (-30dBm to +15dBm in 50) diode detectors. Excellent temperature stability is Frequency Range from 100MHz to 2.5GHz achieved over the full operating range of -40°C to +85°C. Temperature Stable Linear-in-dB Response The choice of three different input voltage ranges elimi-nates the need for external attenuators, thus simplifying Fast Response: 70ns 10dB Step PA control-loop design. The logarithmic amplifier is a volt- 10mA Output Sourcing Capability age-measuring device with a typical signal range of -58dBV to -13dBV for the MAX4000, -48dBV to -3dBV for Low Power: 17mW at 3V (typ) the MAX4001, and -43dBV to +2dBV for the MAX4002. Shutdown Current 30µA (max) The input signal for the MAX4000 is internally AC-coupledusing an on-chip 5pF capacitor in series with a 2k input Available in an 8-Bump UCSP and a Small 8-Pin resistance. This highpass coupling, with a corner at µMAX Package 16MHz, sets the lowest operating frequency and allowsthe input signal source to be DC grounded. The Ordering Information MAX4001/MAX4002 require an external coupling capaci-tor in series with the RF input port. These PA controllers PIN- TOP PART TEMP RANGE feature a power-on delay when coming out of shutdown, PACKAGE MARK holding OUT low for approximately 5µs to ensure glitch- MAX4000EBL-T -40°C to +85°C 8 UCSP-8 ABF free controller output.
