Overview
Data Sheet FEATURES Broadband upconverter/downconverter Power conversion gain of 1.
8 dB Broadband RF, LO, and IF ports SSB noise figure (NF) of 9.
75 dB Input IP3: 28.
5 dBm Input P1dB: 13.
3 dBm Typical LO drive: 0 dBm Single-supply operation: 5 V at 130 mA Adjustable bias for low power operation Exposed paddle, 4 mm × 4 mm, 24-lead LFCSP package APPLICATIONS Cellular base station receivers Radio link downconverters Broadband block conversion Instrumentation GENERAL DESCRIPTION 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.
