GENERAL DESCRIPTION

The ADL5811 uses revolutionary new broadband, square

wave limiting, local oscillator (LO) amplifiers to achieve an

unprecedented radio frequency (RF) bandwidth of 700 MHz

to 2800 MHz. Unlike conventional narrow-band sine wave LO

amplifier solutions, this permits the LO to be applied either

above or below the RF input over an extremely wide bandwidth.

Because energy storage elements are not used, the dc current

consumption also decreases with decreasing LO frequency.

wideband applications where in-band blocking signals may

otherwise result in the degradation of dynamic range. Blocker

noise figure performance is comparable to narrow-band passive

mixer designs. High linearity IF buffer amplifiers follow the

passive mixer cores, yielding typical power conversion gains of

7.5 dB, and can be used with a wide range of output

impedances. For low voltage applications, the ADL5811 is

capable of operation at voltages down to 3.6 V with

substantially reduced current. Two logic bits are provided to

power down (<1.5 mA) the circuit when desired.

The ADL5811 uses highly linear, doubly balanced, passive

mixer cores along with integrated RF and LO balancing circuits

to allow single-ended operation. The ADL5811 incorporates

programmable RF baluns, allowing optimal performance over a

700 MHz 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

All features of the ADL5811 are controlled via a 3-wire serial

port interface, resulting in optimum performance and

minimum external components.

The ADL5811 is fabricated using a BiCMOS high performance

IC process. The device is available in a 32-lead, 5mm × 5mm,

LFCSP package and operates over a −40°C to +85°C

intermodulation performance over the full RF bandwidth.

The balanced mixer cores also provide extremely high input

linearity, allowing the device to be used in demanding

temperature range. An evaluation board is also available.
