50MHz to 1000MHz, 75dB Logarithmic Detector/Controller
General Description
The MAX2014 complete multistage logarithmic amplifier is designed to accurately convert radio-frequency (RF) signal power in the 50MHz to 1000MHz 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 receivedsignal-strength indication (RSSI) for terminal devices. The MAX2014 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 -40C to +85C operating range. Complete RF Detector/Controller 50MHz to 1000MHz Frequency Range Exceptional Accuracy Over Temperature High Dynamic Range 2.7V to 5.25V Supply Voltage Range* Scaling Stable Over Supply and Temperature Variations Controller Mode with Error Output Shutdown Mode with Typically 1A of Supply Current Available in 8-Pin TDFN Package

MAX2014
Note 1: The MAX2014 is guaranteed by design for TA = -40C to +85C, 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 T A = -40C and +85C, relative to the curve at TA = +25C. 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.

50MHz to 1000MHz, 75dB Logarithmic Detector/Controller MAX2014
Detailed Description
The MAX2014 is a successive detection logarithmic amplifier designed for use in RF power measurement and AGC applications with a 50MHz to 1000MHz frequency range from a single 2.7V to 3.6V power supply. It is pin compatible with other leading logarithmic amplifiers. The MAX2014 provides for improved performance with a high 75dB dynamic range at 100MHz, and exceptional accuracy over the extended temperature range and supply voltage range.
Applications Information
Detector (RSSI) Mode
In detector mode, the MAX2014 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 = 0; see Figure 1). By connecting SET directly to OUT, the op amp gain is set to 2V/V due to two internal 20k feedback resistors. This provides a detector slope of approximately 18mV/dB with a 0.5V to 1.8V output range.

RF Input
The MAX2014 differential RF input (INHI, INLO) allows for broadband signals between 50MHz and 1000MHz. For single-ended signals, AC-couple INLO to ground. The RF inputs are internally biased and need to be ACcoupled using 680pF capacitors as shown in Figures 1 and 2. An internal 50 resistor between INHI and INLO provides a good 50MHz to 1000MHz 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 20k 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 MAX2014 requires power-supply bypass capacitors connected close to each VCC pin. At each VCC pin, connect a 0.1F 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 = 0 (see the typical application circuits, Figures 1 and 2 ). For power-supply voltages (VS) between 4.75V and 5.25V, set R4 = 75 1% (100ppm/C max) and PWDN must be connected to GND.

Power-Down Mode
The MAX2014 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 1A. For normal operation, drive PWDN with a logiclow. It is recommended when using power-down that an RF signal not be applied before the power-down signal is low.
*RSSI mode only. **VS = 2.7V to 3.6V.

Controller Mode
The MAX2014 can also be used as a detector/controller within an AGC loop. Figure 3 depicts one scenario where the MAX2014 is employed as the controller for a variable-gain PA. As shown in the figure, the MAX2014 monitors the output of the PA through a directional coupler. An internal integrator (Figure 2) compares the detected signal with a reference voltage determined by VSET. The integrator, acting like a comparator, increases or decreases the voltage at OUT, according to how closely the detected signal level matches the VSET reference. The MAX2014 adjusts the power of the PA to a level determined by the voltage applied to SET. With R1 = 0, the controller mode slope is approximately 19mV/dB (RF = 100MHz).

Layout Considerations
As with any RF circuit, the layout of the MAX2014 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.
