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

The MAX4000/MAX4001/MAX4002 family is available in  
an 8-pin µMAX package and an 8-bump chip-scale pack-  
age (UCSP™). The device consumes 5.9mA with a 5.5V  
supply, and when powered down the typical shutdown  
current is 13µA.
