ADL5801 — High-linearity, wideband active mixer with adaptive bias and optional power detection Key benefits High linearity and wide dynamic range: The double symmetrical active mixer core delivers improved input power handling and high dynamic-range frequency conversion across 10 MHz to 6 GHz, reducing distortion in demanding RF environments. Easy optimization for different conditions: A single adaptive bias control pin lets you trade off input linearity, single‑sideband (SSB) noise performance, and DC current to match varying operating points without complex external circuitry. Adaptive performance monitoring: The optional built-in input power detector enables the mixer to adjust bias automatically as input power changes, maintaining optimal linearity and noise performance across dynamic signal conditions. Low leakage and reduced spurs: The symmetrical active mixer topology provides excellent LO-to-RF and LO-to-IF leakage, typically better than −40 dBm, minimizing LO feedthrough and preserving signal integrity. Core functions and attributes Function: Active double-balanced mixer for RF-to-IF and frequency conversion applications. Frequency compatibility: Operates from 10 MHz up to 6 GHz, making it suitable for a broad range of wireless bands and systems. Control interface: Single-pin adaptive bias control for straightforward tuning of linearity, SSB noise ratio, and DC current. Built-in detection: Optional input power detector supports adaptive bias schemes and closed-loop performance control. Performance highlight: Typical LO-to-RF and LO-to-IF leakage better than −40 dBm; designed to minimize signal degradation during conversion. Why customers choose the ADL5801 Simplifies design trade-offs: The single bias control simplifies tuning for scenarios where either maximum linearity or lower power consumption is required, removing the need for multiple external adjustments. Robust across deployments: Wideband coverage and high dynamic range reduce the need for multiple mixer types in multi-band systems. Lower downstream complexity: Low LO leakage reduces filtering requirements and eases integration into sensitive receiver chains. Practical use scenarios Wireless infrastructure and repeaters: Use the ADL5801 in base station receivers, repeaters, or transceivers that require wideband conversion and strong linearity to handle high-power interferers without excessive distortion. RF test and measurement gear: Integrate into spectrum analyzers or signal generators that demand low LO feedthrough and adjustable biasing to characterize signals across 10 MHz–6 GHz. Microwave links and multi-band radios: Deploy in point-to-point microwave radios, multi-band RF front ends, and commercial radio systems where adaptive biasing and low spurious leakage improve link reliability and reduce filtering overhead. What sets it apart The combination of a double symmetrical active mixer core, single-pin adaptive bias control, and optional built-in power detection provides a compact, flexible solution for high-performance frequency conversion across a very broad frequency range while minimizing LO leakage and easing system-level design trade-offs.
