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.
