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.
