Quasi differential 100 Ω output interface suitable to drive 100 Ω 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 Ω differential output 500 MHz envelope bandwidth and a fast, 0.6 ns rise time makes impedance designed to drive a 100 Ω 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 oscil ator (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 external y The response of the ADL6012 is stable over a wide frequency applied voltage to the VOCM interface. This configuration range and features excellent temperature stability. Enabled by simplifies interfacing to a high speed analog-to-digital propriety technology, the device independently detects the converter (ADC). positive and the negative envelopes of the RF input. Even order The ADL6012 is specified for operation from −55°C to +125°C, 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.
