Description  
Alpha beam–lead and chip Schottky barrier mixer  
diodes are designed for applications through 40 GHz  
in Ka–band. The beam–lead design eliminates the  
problem of bonding to the very small junction area  
that is characteristic of the low capacitance involved  
in microwave devices.  
Beam–lead and chip Schottky barrier diodes are  
categorized by noise figure for mixer applications in  
four frequency ranges: S, X, Ku and Ka–bands.  
However, they can also be used as modulators, high  
speed switches and low power limiters.  
Several types of semiconductor–barrier metal  
systems are available, thus allowing proper selection  
for optimum mixer design. For most applications the  
N–type silicon, low drive types are preferable,  
especially for starved LO mixers.  
Beam–lead Schottky barrier mixer diodes are made  
by the deposition of a suitable barrier metal on an  
epitaxial silicon substrate to form the junction. The  
process and choice of materials result in low series  
resistance along with a narrow spread of capacitance  
values for close impedance control.  
Beam–lead diodes are ideally suited for balanced  
mixers, since they exhibit low parasitics and are  
extremely uniform. A typical V vs. I curve is shown  
F
F
in Figure 1. Typical noise figures vs LO drive is shown  
in Figure 2 for single N–type, low drive diode types.  
A variety of forward knees are available, ranging from  
a low value for low, or starved, local oscillator drive  
levels to a higher value for high drive, low intermode  
mixer applications. The beam–lead diodes are  
available in a wide range of packages as shown.  
Capacitance ranges and series resistances are  
comparable with the packaged devices that are  
available through K–band. The unmounted diodes  
are especially well suited for use in microwave  
integrated circuits. The mounted devices can be  
easily inserted as hybrid elements in stripline,  
microstrip or other such circuitry.
