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 overall 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 source The ADL6010ACPZN is specified for operation from 40C to input impedance, ranges from 30 dBm to +15 dBm. The +85C, and the ADL6010SCPZN is specified for operation from corresponding input voltage amplitudes of 11.2 mV to 1.8 V 55C to +125C.
