General Description
HMC981LP3E achieves excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures usually employed to prevent RF performance degradation due to such variations.
The HMC981LP3E is housed in an RoHS compliant 3x3 mm QFN leadless package with an exposed backside pad to improve thermal characteristics.
