MAXIM MAX2015 Technical data

General Description

The MAX2015 complete multistage logarithmic amplifier
is designed to accurately convert radio-frequency (RF)
signal power in the 0.1GHz to 3GHz frequency range to
an equivalent DC voltage. The outstanding dynamic
range and precision over temperature of this log ampli­fier make it particularly useful for a variety of base sta­tion and other wireless applications, including
automatic gain control (AGC), transmitter power mea­surements, and received signal strength indication
(RSSI) for terminal devices.

The MAX2015 can also be operated in a controller
mode where it measures, compares, and controls the
output power of a variable-gain amplifier as part of a
fully integrated AGC loop.

This logarithmic amplifier provides much wider mea­surement range and superior accuracy compared to
controllers based on diode detectors, while achieving
excellent temperature stability over the full -40°C to
+85°C operating range.

Note 1: The MAX2015 is guaranteed by design for TA= -40°C to +85°C, as specified.
Note 2: Typical minimum and maximum range of the detector at the stated frequency.
Note 3: Dynamic range refers to the range over which the error remains within the stated bounds. The error is calculated at -40°C

and +85°C, relative to the curve at +25°C.

Note 4: The slope is the variation of the output voltage per change in input power. It is calculated by fitting a root-mean-square

(RMS) straight line to the data indicated by RF input power range.

Note 5: The intercept is an extrapolated value that corresponds to the output power for which the output voltage is zero.

It is calculated by fitting an RMS straight line to the data.

Detailed Description

The MAX2015 is a successive detection logarithmic
amplifier designed for use in RF power measurement
and AGC applications with a 0.1GHz to 3GHz
frequency range from a single 2.7V to 3.6V power
supply. It is pin compatible with other leading logarith­mic amplifiers.

The MAX2015 provides for improved performance with a
high 75dB dynamic range at 100MHz, and exceptional
accuracy over the extended temperature range and sup­ply voltage range.

RF Input

The MAX2015 differential RF input (INHI, INLO) allows
for broadband signals between 100MHz and 3GHz. For
single-ended signals, AC-couple INLO to ground. The
RF inputs are internally biased and need to be AC-cou­pled using 680pF capacitors as shown in Figure 1 and
Figure 2. An internal 50Ω resistor between INHI and
INLO provides a good 50MHz to 3.0GHz match.

SET Input

The SET input is used for loop control when in controller
mode or to set the slope of the output signal (mV/dB)
when in detector mode. The internal input structure of
SET is two series 20kΩ resistors connected to ground.
The center node of the resistors is fed to the negative
input of the internal output op amp.

Power-Supply Connections

The MAX2015 requires power-supply bypass capacitors
connected close to each VCCpin. At each VCCpin,
connect a 0.1µF capacitor (C4, C6) and a 100pF capac­itor (C3, C5) with the 100pF capacitor being closest to
the pin.

For power-supply voltages (VS) between 2.7V and 3.6V,
set R4 = 0Ω (see the typical applications circuits).

For power-supply voltages (VS) between 4.75V and

5.25V, set R4 = 75Ω ±1% (100ppm/°C max) and PWDN
must be connected to GND.

Power-Down Mode

The MAX2015 can be powered down by driving PWDN
with logic high (logic high = VCC). In power-down
mode, the supply current is reduced to a typical value
of 1µA. For normal operation, drive PWDN with a logic
low. It is recommended when using power-down that
an RF signal not be applied before the power-down
signal is low.

Applications Information

Detector (RSSI) Mode

In detector mode, the MAX2015 acts like an RSSI,
which provides an output voltage proportional to the
input power. This is accomplished by providing a feed­back path from OUT to SET (R1 = 0Ω; see Figure 1).

By connecting SET directly to OUT, the op amp gain is
set to 2V/V due to two internal 20kΩ feedback resistors.
This provides a detector slope of approximately
18mV/dB with a 0.5V to 1.8V output range.

Controller Mode

The MAX2015 can also be used as a detector/controller
within an AGC loop. Figure 3 depicts one scenario
where the MAX2015 is employed as the controller for a
variable-gain PA. As shown in the figure, the MAX2015
monitors the output of the PA through a directional cou­pler. An internal integrator (Figure 2) compares the

ref­erence. The MAX2015 adjusts the power of the PA to a
level determined by the voltage applied to SET. With R1 =
0Ω, the controller mode slope is approximately
19mV/dB (RF = 100MHz).

Layout Considerations

As with any RF circuit, the layout of the MAX2015 circuit
affects the device’s performance. Use an abundant num­ber of ground vias to minimize RF coupling. Place the
input capacitors (C1, C2) and the bypass capacitors
(C3–C6) as close to the IC as possible. Connect the
bypass capacitors to the ground plane with multiple vias.
