High-performance UHF SQUID magnetometer

Review of Scientific Instruments, 1979
We describe a lumped-component stabilized point contact SQUID magnetometer, biased at 430 MHz and utilizing a cooled (4.2 K) GaAs FET preamplifier. The system incorporateds a full-bandwidth (5–10 MHz) flux-locked loop and has an overall flux sensitivity of 1×10−5 Φ0/(Hz)1/2, corresponding to an energy sensitivity ≃4.5×10−31 J/Hz.

A monolithic UHF RFID transceiver for mobile UHF RFID readers

2016 International Conference on Integrated Circuits and Microsystems (ICICM), 2016
According to the protocol of ISO/IEC 18000-6C, a monolithic UHF RFID transceiver is designed, in a standard 0.18gm RF CMOS process, in which a receiver, a transmitter and a frequency synthesizer are integrated. The direct-conversion receiver consists of a LNA, down-conversion mixers, DCOCs, LPFs and PGAs.

UHF STIMULATION SYSTEM

1969
Abstract : A UHF remote stimulation system working in the 915 MHz band is described, which generates current pulses in three stimulation channels. The amplitude, duration, repetition rate and channel can be controlled from a remotely located control panel.

UHF RFID wristbands

This contribution is focused on the performance evaluation of a long-range patch-type antenna for ultra-high frequency (UHF) radiofrequency identification (RFID) wristband tags. The antenna design was presented in the IEEE International Conference on RFID Technology and Applications (RFID-TA), held on September 4-6, 2023, Aveiro, Portugal, under the ...
