GENERAL DESCRIPTION
The ADL5802 utilizes high linearity doubly balanced active
mixer cores with integrated LO buffer amplifiers to provide
high dynamic range frequency conversion from 100MHz to
6GHz. The mixers benefit from a proprietary linearization
architecture which provides enhanced IP3 performance when
subject to high input levels. A bias adjust feature allows the
input linearity, SSB Noise Figure, and DC current to be
optimized using a single control pin. The high input linearity
allows the device to be used in demanding cellular applications
where in-band blocking signals may otherwise result in
degradation in dynamic performance. The balanced active
mixer arrangement provides superb LO to RF and LO to IF
leakage, typically better than -40dBm. The IF outputs are
internally terminated to a 200-Ω source impedance and provide
a typical voltage conversion gain of 7.5 dB when loaded into a
200-Ω load.

The ADL5802 is fabricated using a SiGe high performance IC
process. The device is available in a compact 4mm x 4mm 24-
lead LFCSP package and operates over a 40°C to +85°C
temperature range. An evaluation board is also available.
