GENERAL DESCRIPTION  
The ADL6010 is a versatile, broadband envelope detector  
covering the microwave spectrum. It provides state-of-the-  
art accuracy with very low power consumption (8 mW) in a  
simple, easy to use 6-lead format. The output is a baseband  
voltage proportional to the instantaneous amplitude of the radio  
frequency (RF) input signal. It exhibits minimal slope variation  
of the RF input to envelope output transfer function from  
0.5 GHz to 43.5 GHz.  
A subtle aspect of the balanced detector topology is that no  
even-order distortion, caused by nonlinear source loading,  
occurs at the input. This is an important benefit in applications  
where a low ratio coupler is used to extract a signal sample and  
is a significant improvement over traditional diode detectors.  
The power equivalent of a fluctuating RF input amplitude can  
be extracted by the addition of an rms-to-dc converter IC.  
Alternatively, the baseband output can be applied to a suitably  
fast analog-to-digital converter (ADC) and the rms value (and  
other signal metrics, such as peak to average ratio) calculated in  
the digital domain.  
The detector cell uses a proprietary eight Schottky diode array  
followed by a novel linearizer circuit that creates a linear  
voltmeter with an overall scaling factor (or transfer gain) of  
nominally ×2.2 relative to the voltage amplitude of the input.  
The output response accuracy is insensitive to variation in the  
supply voltage, which can range from 4.75 V to 5.25 V. The  
ultralow power dissipation contributes to its long-term stability.  
Although the ADL6010 is not inherently a power responding  
device, it remains convenient to specify the input in this way.  
Thus, the permissible input power, relative to a 50 Ω source input  
impedance, ranges from −30 dBm to +15 dBm. The corresponding  
input voltage amplitudes of 11.2 mV to 1.8 V generate quasi-dc  
outputs from about 25 mV to 4 V above common (COMM).  
The ADL6010A is specified for operation from −40°C to +85°C,  
and the ADL6010S is specified for operation from −55°C to  
+125°C. Both are available in a 6-lead, 2 mm × 2 mm LFCSP  
package.
