The ADL6010 is a versatile, broadband envelope detector topology is that no even-order distortion, caused by nonlinear covering the microwave spectrum. It provides state-of-the- source loading, occurs at the input. This is an important benefit art accuracy with very low power consumption (8 mW) in a in applications where a low ratio coupler is used to extract a simple, easy to use 6-lead format. The output is a baseband signal sample and is a significant improvement over traditional voltage proportional to the instantaneous amplitude of the diode detectors. radio frequency (RF) input signal. It exhibits minimal slope The power equivalent of a fluctuating RF input amplitude can variation of the RF input to envelope output transfer function be extracted by the addition of an rms-to-dc converter IC. from 0.5 GHz to 43.5 GHz. Alternatively, the baseband output can be applied to a suitably The detector cell uses a proprietary eight Schottky diode array fast analog-to-digital converter (ADC) and the rms value (and followed by a novel linearizer circuit that creates a linear voltmeter other signal metrics, such as peak to average ratio) calculated in with an overal scaling factor (or transfer gain) of nominally ×2.2 the digital domain. relative to the voltage amplitude of the input. The output response accuracy is insensitive to variation in the Although the ADL6010 is not inherently a power responding supply voltage, which can range from 4.75 V to 5.25 V. The device, it remains convenient to specify the input in this way. ultralow power dissipation contributes to its long-term stability. Thus, the permissible input power, relative to a 50 Ω source The ADL6010ACPZN is specified for operation from −40°C to input impedance, ranges from −30 dBm to +15 dBm. The +85°C, and the ADL6010SCPZN is specified for operation from corresponding input voltage amplitudes of 11.2 mV to 1.8 V −55°C to +125°C. Both are available in a 6-lead, 2 mm × 2 mm generate quasi-dc outputs from about 25 mV to 4 V above LFCSP package. common (COMM). A subtle aspect of the balanced detector
