Silicon Schottky Barrier Diodes: Packaged, Bondable Chips

and Beam Leads

Applications

 Detectors

 Mixers

Features

 Available in both P-type and N-type low barrier designs

 Low 1/f noise

 Large bond pad chip design

 Planar passivated beam-lead and chip construction

efficiency during manual operations, and is ideal for automated

assembly.

 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
