Product Details

The ADL6012 is a versatile, broadband Envelope detector covering the microwave frequencies from 2 to 43.5 GHz. It provides state-of-the-art accuracy with low power consumption (110 mW at 3.3V) in a simple, easy to use 10-lead LFCSP package. The envelope output is pseudo-differential with 500 MHz BW and variable common-mode capability.

The detector cell uses a proprietary Schottky diode array to extract both the positive and the negative envelopes of the RF signal. These two envelope voltages are buffered and level shifted using an externally applied VOCM voltage and presented on the VENV+ and VENV- pins. The envelope outputs are designed to drive 400 Ω differential load and up to 2pF of capacitance to ground on each output. The envelope output bears the signature of typical diode non-linearity and has 20dB linear range at the top end.

The input power can range from −15 dBm to +15 dBm.

A subtle aspect of the balanced detector topology used in ADL6012 is that even-order distortion, caused by nonlinear source loading, at the input is substantially reduced compared with a simple diode detector. This is an important benefit in applications where a low ratio coupler is used to extract a signal sample. This is a significant improvement over traditional diode detectors.

The Envelope output can be used to detect and correct LO leakage in IQ modulators in point-to-point Microwave radios, employing higher order QAM modulations, where LO leakage in the transmit signal causes EVM degradation. The ADL6012 envelope detector outputs can also be used in extremely fast signal detection applications where log or RMS responding detection capability, is not needed.

The ADL6012 is specified for operation from −40°C to +85°C. The ADL6012 is available in a 10-lead, 3 mm × 2 mm LFCSP package.
