The ADL6012 is a versatile, broadband envelope detector that operates from 2 GHz to 67 GHz. The combination of a wide, 500 MHz envelope bandwidth and a fast, 0.6 ns rise time makes the device suitable for a wide range of applications, including wideband envelope tracking, transmitter local oscillator (LO) leakage corrections, and high resolution pulse (radar) detection.
The response of the ADL6012 is stable over a wide frequency range and features excellent temperature stability. Enabled by propriety technology, the device independently detects the positive and the negative envelopes of the RF input. Even order distortion at the RF input due to nonlinear source loading is also reduced when compared to classic diode detector architectures.
The quasi differential output interface formed by the VENV+ and VENV− pins has a matched, 100 Ω differential output impedance designed to drive a 100 Ω differential load and up to 2 pF of capacitance to ground on each output. The output interface provides the detected and amplified positive and negative envelopes, which are level shifted using an externally applied voltage to the VOCM interface. This configuration simplifies interfacing to a high speed analog-to-digital converter (ADC).
The ADL6012 is specified for operation from −55°C to +125°C, and is available in a 10-lead, 3 mm × 2 mm LFCSP.

Evaluation Kits (1)
The ADL6012-EVALZ provides efficient evaluation of the ADL6012 2 GHz to 67 GHz envelope detector. The ADL6012 has fast rise time and fall time responses, around 1 ns depending on input power levels, with an output envelope bandwidth of 500 MHz. The ADL6012-EVALZ provides the basic connections for the RF input signal and the envelope output voltage. Differential envelope outputs on the ADL6012-EVALZ can be directly connected to a high speed oscilloscope to evaluate the differential envelope tracking capabilities.
For full details on the ADL6012, see the ADL6012 data sheet. Consult the ADL6012 data sheet in conjunction with this user guide when using the ADL6012-EVALZ evaluation board.
