DATA SHEET  
DME, DMF, DMJ Series: Silicon Beam-Lead Schottky Mixer  
Diodes – Singles, Pairs & Quads, Bondable & Packaged Chips  
Applications  
x Microwave Integrated Circuits  
x Mixers  
x Detectors  
Features  
x Low 1/f noise  
x Low intermodulation distortion  
x Epoxy and hermetically sealed packages  
x Statistical Process Control wafer fabrication  
x Packages rated MSL1, 260 qC per JEDEC J-STD-020)  
Beam-lead Schottky barrier diodes are categorized by universal  
mixer applications in four frequency ranges: S, C, X, Ku, K, and Ka  
bands as noted in Table 1. They may also be used as modulators  
and high-speed switches.  
Skyworks offers lead (Pb)-free, RoHS (Restriction of  
Hazardous Substances) compliant packaging.  
Beam-lead diodes are suited for balanced mixers, due to their low  
parasitics and uniformity.  
The absolute maximum ratings of the DME, DMF, and DMJ series  
of Schottky mixer diodes are provided in Table 2. Electrical and  
physical specifications are provided in Tables 3 through 15.  
Description  
Skyworks beam-lead silicon Schottky barrier mixer diodes are  
designed for applications through 40 GHz. The beam-lead design  
reduces the problem of bonding to the very small area  
characteristic of low capacitance junctions.  
Typical performance characteristics are shown in Figures 1  
through 3. Typical mixer circuits are shown in Figure 4.  
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 with a narrow spread of  
capacitance values for close impedance control.

Frequency Band  
(GHz)  
A variety of forward voltages are available ranging from low values  
for low, or starved, local oscillator drive levels to high values for high  
drive, low distortion mixer applications. Beam-lead diodes are  
available in a wide range of packages. Capacitance ranges and  
series resistances are comparable with the packaged devices that  
are available up to, and including, the Ka-band. Unpackaged diodes  
are well suited for use in Microwave Integrated Circuits (MICs). The  
packaged devices are designed to be inserted as hybrid elements in  
strip, transmission line applications.
