ADL5801 - ADI Function Overview

Product Details
The ADL5801 uses a high linearity, doubly balanced, active mixer core with integrated LO buffer amplifier to provide high dynamic range frequency conversion from 10 MHz to 6 GHz. The mixer benefits 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. An optional input power detector is provided for adaptive bias control. 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 adaptive bias feature allows the part to provide high input IP3 performance when presented with large blocking signals. When blockers are removed, the ADL5801 can automatically bias down to provide low noise figure and low power consumption.
The balanced active mixer arrangement provides superb LO-to-RF and LO-to-IF leakage, typically better than −40 dBm. The IF outputs are designed to provide a typical voltage conversion gain of 7.8 dB when loaded into a 200 Ω load. The broad frequency range of the open-collector IF outputs allows the ADL5801 to be applied as an upconverter for various transmit applications.
The ADL5801 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.
