The keysight 423b low barrier schottky diode detector has been widely used for many years in a variety of applications including leveling and power sensing.
Schottky diode ghz. The graph indicate the operating optimal frequency range of a schottky diode in relation to the junction capacitance. Zero bias schottky diode detectors 100 khz 50 ghz page 2 2 specifications. Small area schottky diodes are the heart of rf detectors and mixers which often operate at frequencies up to 50 ghz.
It offers good performance and ruggedness. The area between the two curves is the recommended range of max. Bypass capacitor c is chosen to be 1 nf so that it has low ohmic capacitive reactance up to 6 ghz.
It offers good performance and ruggedness. These devices are available in die form surmount tm flip chip plastic and ceramic packaging. Junction capacities for the desired frequency.
Matched pairs option 001 offer very good detector tracking. For silicon metal schottky diodes the reverse voltage is typically 50 v or less. Schottky mixer and detector diodes at macom we produce a wide variety of schottky diodes as your best choice for microwave circuit detector and mixer applications ranging from dc to 80 ghz.

A video load option 002 extends the square law region to at least 01 mw 10 dbm. Skyworks silicon schottky diode chips are intended for use as detector and mixer devices in hybrid integrated circuits at frequencies from below 100 mhz to higher than 40 ghz.
Skyworks universal chip design features a 4 mil diameter bond pad that is offset from the semiconductor junction preventing damage to the active junction as a result of wire bonding. The most evident limitations of schottky diodes are their relatively low reverse voltage ratings and their relatively high reverse leakage current. Skyworks silicon schottky diode chips are intended for use as detector and mixer devices in hybrid integrated circuits at frequencies from below 100 mhz to higher than 40 ghz.
Matched pairs option 001 offer very good detector tracking. For example at 4 ghz the optimum junction capacitance is 1pf. The keysight 8472b low barrier schottky diode lbsd detector has been widely used for many years in a variety of applications including leveling and power sensing.
Usually the diode based detectors can achieve broadband performance. Rf and microwave power detection with schottky diodes single diode detector circuit 2 single diode detector circuit a single schottky diode detection circuit is shown in figure 2.
