The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

If you ever look at construction notes for building old detector type radios the type of headphones specified always have an impedance of 2 × 2000Ω. Nowadays the most commonly available headphones ...

Abstract: Radiofrequency receivers based on energy detection usually require bulky and costly antenna filters. A promising alternative comes from spin-torque diodes that inherently provide both ...

Back in 1966, a suitable toy for a geeky kid was a radio kit. You could find simple crystal radio sets or some more advanced ...

Abstract: Signal detection at (sub-)mm-wave frequencies via a single chip size component is discussed. The monolithic integration consists of high current density InP-based Triple Barrier Resonant ...

Fairview Microwave Inc. recently released a full line of coaxial-packaged tunnel diode detectors that are are well-suited for proof-of-concept and prototype applications. Such application areas ...

Agilent Technologies Inc. has announced the launch of 1200 Series diode-array and multiple-wavelength detectors featuring improved noise specifications. These liquid chromatography detectors are ...
