Among the topics are the origins of electronic mixers, semiconductor modeling, diode mixer
theory, bipolar junction transistor theory and applications, and passive and active field effect transistor applications.
The signal reflected from the tuning fork is delected in the diode mixer and subsequently filtered to yield only the difference frequency, similar to what happens for the signal returned from the moving target vehicle (see Sec.
As we did for the tuning fork (which is a case describing phase modulation), we use the approximation to the diode equation response to find that the frequencies of the signal output from the diode mixer and filter are at [+ or -][f.
The value of [delta]f in current DTR radars is computed from the periodic sampling of the difference frequency output from the diode mixer.

NASDAQ:WJCI), a leading designer and supplier of radio frequency (RF) products and solutions for the wireless infrastructure and radio frequency identification (RFID) reader markets, today announced its expansion of the high-dynamic range, low-cost WJZ diode mixer series, a family of second source frequency mixers created as pin-for-pin drop in replacement for popular diode-based frequency mixers.
Market response to our second source family of products, in particular the WJZ diode mixer family, has been tremendous.
Utilizing WJ's RF expertise and leadership in wireless infrastructure, WJ developed the WJZ diode mixer family.
They are able to achieve the performance of a double balanced diode mixer
in an ultra-miniature SOT-25 package.
WJ's mixers feature high input IP3 performance for broadband communication applications and span a broad range of technologies from FETs and MMIC mixers to diode mixers
These Quad-MOSFET mixers offer the affordability of diode mixers
with the quality and performance of GaAs MESFET MMIC mixers," stated Skip Hoover, Executive Vice President of Sales at WJ Communications.
The vertical structure of TRW's HBT Schottky diode mixers
makes it possible to deliver low conversion loss, high port-to-port isolation, and minimal MMIC-to-MMIC variation.
