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 up-converter for various transmit applications.
The ADL5801 is fabricated using a high performance IC process for SiGe.
The device is available in a compact 4 mm x 4 mm, 24-lead LFCSP package and operates over a -40°C to +85°C temperature range. An evaluation board is also available.
