Overview
The HMC442 is a GaAs PHEMT MMIC medium power amplifier operating between 17.5 and 25.5 GHz. It provides 15 dB of gain, a saturated output power (Psat) of +23 dBm, and a noise figure of 9 dB. The device requires a +5V supply voltage with a typical current consumption of 84 mA. Key performance metrics include a P1dB of 22 dBm and a power added efficiency (PAE) of 25%. It is housed in a compact 12-SMT package.
Feature Summary
- Utilizes efficient GaAs PHEMT MMIC technology for high-performance amplification
- Designed for medium power applications within the K-band frequency range
- Offers high gain and saturation power in a small surface-mount footprint
Applications
- Point-to-point radio links
- Electronic warfare systems
- Test and measurement equipment
Procurement Notes
Verify the specific suffix (e.g., LC3BTR) to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status as required by your assembly process. Check for limited availability or restricted distribution channels directly with Analog Devices or authorized distributors, as stock levels may vary significantly.
Selection Notes
Select this component when a medium power solution is needed for frequencies up to 25.5 GHz. Consider the 15 dB gain and +23 dBm Psat for link budget calculations. Ensure the design supports a +5V supply and manages thermal dissipation for the QFN-12 package. Compare against other HMC4xx series devices if different gain or power levels are required.
Part Context
The HMC442 belongs to the HMC442G series of RF amplifiers manufactured by Analog Devices. It is part of a family of GaAs MMICs designed for wireless infrastructure and defense applications. The device represents a balance of gain, power, and efficiency for millimeter-wave operations.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct replacements or pin-compatible alternatives within the HMC4xx series.
