The ADL5511 is an RF envelope and TruPwr^™ rms detector. The envelope output voltage is presented as a voltage that is proportional to the envelope of the input signal. The rms output voltage is independent of the peak-to-average ratio of the input signal.

The rms output is a linear-in-V/V voltage with a conversion gain of 1.9 V/V rms at 900 MHz. The envelope output has a conversion gain of 1.46 V/V at 900 MHz and is referenced to an internal 1.1 V reference voltage, which is available on the EREF pin.

The ADL5511 can operate from dc to 6 GHz on signals with envelope bandwidths up to 130 MHz.

The extracted envelope can be used for RF power amplifier (PA) linearization and efficiency enhancements and the rms output can be used for rms power measurement. The high rms accuracy and fast envelope response are particularly useful for envelope detection and power measurement of broadband, high peak-to-average signals that are used in CDMA2000, W-CDMA, and LTE systems.

The ADL5511 operates from −40°C to +85°C and is available in a 16-lead, 3 mm × 3 mm LFCSP package.

APPLICATIONS

RMS power and envelope detection of W-CDMA, CDMA2000, LTE, and other complex waveforms

Product Details

ADL5511-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a 5 V/100 mA power supply. The 5 V power supply should be connected to the clip leads labeled VPOS and GND. The RF input signals are applied to an edge-mounted SMA type RF connector (RFIN). The envelope output signal is accessible via the SMA connector labeled VENV. The RMS output and envelope reference signals are accessible on the clip leads labeled VRMA and EREF. To access the RMS output and envelope reference output via SMA cables, SMA connectors can be soldered on to the pads labeled VRMS1 and EREF1.
