GENERAL DESCRIPTION
The ADL5811 uses a revolutionary new broadband square wave
limiting LO amplifier to achieve an unprecedented RF
bandwidth of 700 to 2800MHz. Unlike conventional
narrowband sinewave LO amplifier solutions, this permits the
LO to be applied either above or below the RF input over an
extremely wide bandwidth. Since energy storage elements are
not utilized, the DC current consumption also decreases with
decreasing LO frequency.
The ADL5811 utilizes a highly linear doubly balanced passive
mixer core along with integrated RF and LO balancing circuitry
to allow for single-ended operation. The ADL5811 incorporates
a programmable RF balun allowing for optimal performance
over a 700 to 2800 MHz RF input frequency. The balanced
passive mixer arrangement provides outstanding LO to RF and
LO to IF leakages, excellent RF to IF isolation, and excellent
intermodulation performance over the full RF bandwidth. The

RFCT
balanced mixer core also provides extremely high input
linearity allowing the device to be used in demanding wideband
applications where in-band blocking signals may otherwise
result in the degradation of dynamic range. Blocker Noise
Figure performance is comparable to narrowband passive mixer
designs. A high linearity IF buffer amp follows the passive mixer
core, to yield a typical power conversion gain of 7.5dB, and can
be utilized with a wide range of output impedances.
voltage applications, the ADL5811 is capable of operation at
voltages down to 3.6V with substantially reduced current.
logic pin is provided to power down (<100uA) the circuit when
desired.
The ADL5811 is fabricated using a BiCMOS high performance
IC process. The device will be available in a 5mm x 5mm 32-
lead LFCSP package and operates over a −40°C to +85°C
temperature range. An evaluation board is also available.
