HMC1131LC4

Overview

The HMC1131LC4 is a GaAs pHEMT MMIC driver amplifier operating from 24 GHz to 35 GHz. It delivers 22 dB gain at 24-27 GHz, with a saturated output power (PSAT) of 25 dBm and an output P1dB of 24 dBm. The device features a high output third-order intercept point (IP3) of 35 dBm. Powered by a 5 V supply, it draws 225 mA. The component is housed in a compact 24-pin, 4 mm × 4 mm LCC package.

Feature Summary

• Utilizes GaAs pHEMT technology for high-performance microwave amplification
• Provides high linearity with significant output IP3 capabilities
• Designed as a compact driver amplifier for millimeter-wave frequencies

Applications

• Point-to-point radio systems
• VSAT communications
• SATCOM applications

Procurement Notes

Verify the specific ordering suffix LC4 against Analog Devices official documentation to confirm pinout and package compatibility. Ensure that the procurement channel provides valid traceability for this MMIC component. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit products. Confirm that the received unit matches the specified 24-VFQFN exposed pad configuration before integration into RF designs.

Selection Notes

Select this component when designing drivers for 24-35 GHz bands requiring high linearity and moderate power output. The 22 dB gain and 35 dBm IP3 make it suitable for maintaining signal integrity in point-to-point links. Consider the 5 V/225 mA power budget and the 4x4 mm footprint constraints during PCB layout. This MMIC is appropriate for VSAT and SATCOM uplink stages where compact size and performance are critical.

Part Context

The HMC1131LC4 belongs to Analog Devices' family of GaAs pHEMT MMICs designed for millimeter-wave applications. It serves as a driver amplifier within the broader HMC series, which includes various frequency-specific models. The LC4 suffix typically denotes a specific tape-and-reel packaging variant or lead-free processing status, distinct from the bare die or other package options like the standard HMC1131.

Replacement Considerations

Direct substitutes include the HMC1131, which shares identical electrical specifications but may differ in packaging or reel format. Verify that any replacement maintains the 24-35 GHz operational range and 24-pin LCC footprint. Ensure thermal and DC characteristics match the original design requirements.
