MAX9995ETX

RF Mixers Overview

The MAX9995ETX is a dual, SiGe, high-linearity downconversion mixer IC designed for operation within the 1.7GHz to 2.2GHz frequency range. It features an integrated LO buffer/switch and provides 6.1dB gain with a typical noise figure of 9.9dB. The device operates on a single supply voltage between 4.75V and 5.25V, drawing approximately 380mA of current. Packaged in a compact 36-TQFN (6x6) surface-mount format, it supports applications requiring high linearity and low noise performance.

• Low noise figure specification for improved receiver sensitivity
• Single-supply operation simplifying power management design

RF Mixers Applications

• WCDMA base station receivers
• TD-SCDMA communication systems
• LTE and TD-LTE infrastructure
• GSM/EDGE network equipment
• PCS and UMTS wireless local loop applications

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated channels due to discontinuation status. Confirm package marking and lot traceability against official datasheets. Check for RoHS compliance documentation as indicated by the '+' suffix. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

RF Mixers Selection Notes

Select this component when dual-channel downconversion with integrated LO distribution is required in the 1.7-2.2GHz band. Consider the 36-TQFN footprint for space-constrained PCB layouts. Evaluate thermal dissipation capabilities given the 380mA supply current. Compare linearity metrics against system dynamic range requirements before finalizing the design choice.

RF Mixers Part Context

The MAX9995 belongs to Maxim Integrated's family of high-performance RF mixers. It utilizes Silicon-Germanium technology to achieve superior linearity and noise characteristics compared to standard silicon alternatives. The ETX variant specifically denotes the tape-and-reel packaging option within the TQFN form factor, facilitating automated surface-mount assembly processes.

RF Mixers Replacement Considerations

The MAX9995ETX+T serves as the reel-pack equivalent of the tube-packaged MAX9995ETX. Verify pin compatibility and electrical specifications remain identical across these variants. No direct functional substitutes are documented; consider redesigning for newer generation mixers if long-term availability is critical.
