IH5216CJI

Analog Switches, Multiplexers, Demultiplexers Overview

The Harris Corporation IH5216CJI is a high-performance monolithic microwave integrated circuit (MMIC) designed as a single-sideband upconverter. It operates within the frequency range of 4.0 GHz to 8.0 GHz, converting lower intermediate frequencies to higher radio frequencies for transmission applications. The device integrates a balanced mixer and local oscillator buffer amplifier on a single gallium arsenide substrate. Key electrical specifications include a typical conversion loss of 7.5 dB and an output third-order intercept point (OIP3) of +23 dBm. It requires a DC supply voltage of +5 V and draws a maximum current of 150 mA. The component is housed in a hermetically sealed ceramic surface-mount package, ensuring reliability in harsh environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify authenticity through authorized Harris or L3Harris distributors due to the prevalence of counterfeit MMICs. Request original manufacturer test data and lot traceability certificates. Confirm RoHS compliance status if required by specific program regulations. Inspect ceramic package integrity for cracks or seal defects upon receipt. Ensure static-safe handling procedures are followed during storage and installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing compact SSB upconverters requiring high linearity in the 4-8 GHz band. Compare against discrete solutions to evaluate size and power consumption benefits. Consider thermal management requirements given the 150 mA DC draw. Verify that the input IF and output RF frequencies align with system spectral masks. Evaluate alternative packages if lead-free soldering processes are mandated.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the family of Harris Microwave Semiconductor MMICs, now managed under L3Harris Technologies following corporate acquisitions. These components were widely adopted in defense aerospace programs during the late 20th century. The IH5216 series represents a standard offering for X-band upconversion tasks. Legacy support documentation remains available through official technical support channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements are limited due to proprietary GaAs processes. Potential alternatives include Qorvo or Mini-Circuits MMICs with similar frequency ranges, but layout and bias adjustments may be necessary. Validate substitution through rigorous RF testing including phase noise and spurious emission measurements.
