HMC394LP4TR

Overview

The HMC394LP4TR is a low-noise GaAs HBT programmable 5-bit counter in a 4x4 mm leadless surface mount package. It supports continuous division ratios from 2 to 32 for input frequencies up to 2.2 GHz. The device features an additive SSB phase noise of -153 dBc/Hz at 100 kHz offset, suitable for low-noise frequency synthesizers. It operates on a 5 V supply with 194 mA current consumption and delivers 4 dBm output power.

Feature Summary

• Programmable 5-bit counter architecture enabling flexible frequency division
• Low noise GaAs HBT technology for high-performance signal integrity
• Wide input power range accommodating diverse signal levels
• Compact leadless surface mount packaging for space-constrained designs

Applications

• Satellite communication systems
• Point-to-point radio links
• Local Multipoint Distribution Service (LMDS)
• SONET network infrastructure

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration distinct from bulk or cut tape variants. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the supplier provides valid manufacturer authorization to guarantee component authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when designing frequency synthesizers requiring minimal phase noise degradation. The 2.2 GHz upper frequency limit defines its suitability for microwave applications. Consider the parallel 5-bit control interface requirements for system integration. Evaluate the 4x4 mm footprint against available PCB real estate constraints.
