Packages rated MSL1, 260 C per JEDEC J-STD-020)  
The choice of N- and P-type silicon allows the designer to  
optimize the silicon material for the intended application:  
Skyworks Pb-free products are compliant with  
all applicable legislation. For additional  
information, refer to Skyworks Definition of  
Lead (Pb)-Free, document number SQ04-0073.  
Doppler mixers and high-sensitivity detectors benefit from using  
the low noise characteristics of the P-type silicon.  
Low conversion loss mixers and biased detectors can be  
designed using standard N-type material.  
Description  
Skyworks packaged, beam-lead and chip Schottky barrier  
detector diodes are designed for applications through 40 GHz in  
the Ka band. They 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. P-type silicon is used to obtain superior 1/f  
noise characteristics. N-type silicon is also available.  
Applications  
These diodes are categorized by Tangential Signal Sensitivity  
(TSS) for detector 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.  
TSS is a parameter that describes a diode’s detector sensitivity. It  
is defined as the amount of signal power, below a one-milliwatt  
reference level, required to produce an output pulse with an  
amplitude sufficient to raise the noise fluctuations by an amount  
equal to the average noise level. TSS is approximately 4 dB above  
the minimum detectable signal.  
Packaged diodes are suitable for use in waveguide, coaxial, and  
stripline applications. Beam-lead and chip diodes can also be  
mounted in a variety of packages or on special customer  
substrates.  
The P-type Schottky diodes in this Data Sheet are optimized for  
low noise in the 1/f region. They require a small forward bias (to  
reduce video resistance) if efficient operation is required. The bias  
not only increases sensitivity but also reduces parameter variation  
due to temperature change. Video impedance is a direct function  
of bias and follows the 26/l (mA) relationship. This is important to  
pulse fidelity, since the video impedance together with the  
detector output capacitance affects the effective amplifier  
bandwidth.  
Unmounted beam-lead diodes are especially well suited for use in  
Microwave Integrated Circuit (MIC) applications. Mounted beam-  
lead diodes can be easily used in MIC, stripline, or other such  
circuitry.  
These “universal chips” are designed for a high degree of device  
reliability in both commercial and industrial uses. The offset bond  
pad assures that no mechanical damage occurs at the junction  
during the wire bonding. Additionally, the 4 mil bond pad  
eliminates performance variation due to bonding, improves
