Quasi differential 100 output interface suitable to drive 100 differential load Adjustable output common-mode voltage Flexible supply voltage: 3.15 V to 5.25 V 3 mm 2 mm, 10-lead LFCSP APPLICATIONS Envelope tracking Microwave point to point links Microwave instrumentation Military radios Pulse radar receivers Wideband power amplifier linearization GENERAL DESCRIPTION The ADL6012 is a versatile, broadband envelope detector that The quasi differential output interface formed by the VENV+ operates from 2 GHz to 67 GHz. The combination of a wide, and VENV pins has a matched, 100 differential output 500 MHz envelope bandwidth and a fast, 0.6 ns rise time makes impedance designed to drive a 100 differential load and up to the device suitable for a wide range of applications, including 2 pF of capacitance to ground on each output. The output wideband envelope tracking, transmitter local oscillator (LO) interface provides the detected and amplified positive and leakage corrections, and high resolution pulse (radar) detection. negative envelopes, which are level shifted using an externally applied voltage to the VOCM interface. This configuration The response of the ADL6012 is stable over a wide frequency simplifies interfacing to a high speed analog-to-digital range and features excellent temperature stability. Enabled by converter (ADC). propriety technology, the device independently detects the positive and the negative envelopes of the RF input. Even order The ADL6012 is specified for operation from 55C to +125C, distortion at the RF input due to nonlinear source loading is also and is available in a 10-lead, 3 mm 2 mm LFCSP. reduced when compared to classic diode detector architectures.
