GENERAL DESCRIPTION
The ADL5802 uses high linearity, double-balanced, active mixer
cores with integrated LO buffer amplifiers to provide high
dynamic range frequency conversion from 100 MHz to 6 GHz.
The mixers benefit from a proprietary linearization architecture
that provides enhanced input 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 perform-
ance. The balanced active mixer arrangement provides superb
LO to RF and LO to IF leakage, typically better than −30 dBm.

The IF outputs are designed for a 200 Ω source impedance and
provide a typical voltage conversion gain of 7.6 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 4 mm × 4 mm,
24-lead LFCSP package and operates over a −40°C to +85°C
temperature range. An evaluation board is also available.
