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.
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-toIF leakages, excellent RF-to-IF isolation, and excellent
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
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 (20 dB broadband via serial port

SPURIOUS PERFORMANCE
(N × fRF) − (M × fLO) spur measurements were made using the standard evaluation board. Mixer spurious products are measured in
dBc from the IF output power level. Data was measured only for frequencies less than 6 GHz. Typical noise floor of the measurement
system = −100 dBm.
5 V Performance
VS = 5 V, TA = 25°C, RF power = −10 dBm, LO power = 0 dBm, R1 = 910 Ω, ZO = 50 Ω, optimum SPI settings, unless otherwise noted.
