100MHz to 2500MHz, 45dB RF Detector
in a UCSP
General Description
The MAX4003 low-cost, low-power logarithmic amplifier
is designed to detect the power levels of RF power
amplifiers (PAs) operating from 100MHz to 2500MHz. A
typical dynamic range of 45dB makes this logarithmic
amplifier useful in a variety of wireless applications
including cellular handset PA control, TSSI for wireless
terminal devices, and other transmitter power measure-
ments. This logarithmic amplifier provides much wider
measurement range and superior accuracy than typical
diode-based detectors. Excellent temperature stability is
achieved over the full operating range of -40°C to +85°C.
The MAX4003 logarithmic amplifier is a voltage-mea-
suring device with a typical signal range of -58dBV to
-13dBV. The input signal is internally AC-coupled by an
on-chip 5pF capacitor in series with a 2k ? 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 MAX4003 also
features a power-on delay, which holds the detector
