1. Licensed nursing assistant
Medical · Healthcare Credential Abbreviations
Title for nursing assistants in states such as New Hampshire and Vermont, where they are licensed rather than certified by the state board of nursing. Duties match those of a certified nursing assistant.
Example: Hiring LNAs for evening shift at New Hampshire long-term care center.
Licensure means the board of nursing can discipline aides directly. Requirements include state-approved training and a competency exam. Many LNAs later study to become LPNs or RNs, sometimes with employer tuition support.
2. Low-noise amplifier
Science & Engineering · Electronics & Electrical Abbreviations
Amplifier designed to boost very weak signals from an antenna while adding as little noise as possible, usually placed as the first stage of a radio receiver. LNAs appear in phones, GPS receivers, satellite dishes, radio telescopes and Wi-Fi equipment.
Example: Mounting the LNA at the antenna rather than at the radio improved the weak-signal reception.
Because the first stage's noise dominates the whole receiver chain, as the Friis formula shows, a good LNA sets overall sensitivity. Satellite TV dishes use an LNB, which combines a low-noise amplifier with frequency downconversion. Radio telescope LNAs are often cryogenically cooled.
