2.5GHz 45dB RF-Detecting Controllers
General Description
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.
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.
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.
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.
