IH5053MDE/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The Harris Corporation IH5053MDE/883B is a high-performance monolithic microwave integrated circuit (MMIC) designed for X-band applications. It functions as a low-noise amplifier (LNA) or driver amplifier module, typically housed in a hermetically sealed ceramic package compliant with MIL-PRF-38534 Class K or H specifications. The device operates within the standard military temperature range of -55°C to +125°C. Key electrical characteristics include a noise figure of approximately 2.5 dB and a gain of 20 dB at 10 GHz. It requires a single positive supply voltage, typically around +5V DC, and draws a quiescent current of roughly 60 mA. The component utilizes a gold-plated ceramic surface mount package with edge contacts for thermal and electrical performance.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix code on the component marking against the manufacturer's official datasheet to confirm pinout orientation and exact electrical tolerances. Ensure the supplier provides a Certificate of Conformance (CoC) traceable to MIL-PRF-38534. Check for lead integrity and ceramic package cracks upon receipt, as these are critical failure points in hermetic packages.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a ruggedized, space-qualified MMIC is required for X-band signal conditioning. Compare alternative suppliers such as Raytheon or Mini-Circuits if availability is constrained, ensuring equivalent noise figure and gain flatness across the operational bandwidth. Verify that the system power budget accommodates the specified quiescent current draw.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the family of Harris Semiconductor (now part of L3Harris) MMICs developed for defense electronics. These components were widely used in legacy and modern avionics suites. The /883B suffix indicates processing to MIL-STD-883 standards for microelectronics, ensuring screening for defects common in high-reliability applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements may be limited due to the proprietary nature of the internal die. Potential equivalents should be sought from L3Harris directly or authorized distributors. Cross-reference with similar X-band LNAs from manufacturers like Qorvo or Analog Devices, but verify pin compatibility and thermal resistance differences.
