Description : SURMOUNT™ Low and Medium & High BARRIER Silicon SCHOTTKY DIODEs: Anti-Parallel Pair

Description and Applications
The MA4E2508 SurMountä Anti-Parallel DIODE Series are Silicon Low, Medium & High BARRIER SCHOTTKY Devices fabricated with the patented Heterolithic Microwave Integrated Circuit (HMIC) process. HMIC circuits consist of Silicon pedestals which form DIODEs or via conductors embedded in a glass dielectric, which acts as the low dispersion, low loss, microstrip transmission medium. The combination of silicon and glass allows HMIC devices to have excellent loss and power dissipation characteristics in a low profile, reliable device.
The Surmount SCHOTTKY devices are excellent
choices for circuits requiring the small parasitics of a beam lead device coupled with the superior mechanical performance of a chip. The SurMount structure employs very low resistance silicon vias to connect the SCHOTTKY contacts to the metalized mounting pads on the bottom surface of the chip. These devices are reliable, repeatable, and a lower cost performance solution to conventional devices. They have lower susceptibility to electrostatic discharge than conventional beam lead SCHOTTKY DIODEs.
The multi-layer metalization employed in the fabrication of the Surmount SCHOTTKY junctions includes a platinum diffusion BARRIER, which permits all devices to be subjected to a 16-hour non-operating stabilization bake at 300°C.
The “ 0502 ” outline allows for Surface Mount placement and multi- functional polarity orientations.
The MA4E2508 Family of SurMount SCHOTTKY DIODEs are recommended for use in microwave circuits through Ku band frequencies for lower power applications such as mixers, sub-harmonic mixers, detectors and limiters. The HMIC construction facilitates the direct replacement of more fragile beam lead DIODEs with the corresponding Surmount DIODE, which can be connected to a hard or soft substrate circuit with solder.

Features
● Extremely Low Parasitic Capitance and Inductance
● Surface Mountable in Microwave Circuits, No Wirebonds Required
● Rugged HMIC Construction with Polyimide Scratch Protection
● Reliable, Multilayer Metalization with a Diffusion
BARRIER, 100% Stabilization Bake (300°C, 16 hours)
● Lower Susceptibility to ESD Damage

Description : Medium BARRIER SCHOTTKY Mixer DIODEs

[MicroMetrics, Inc.]

Description
The MicroMetrics MNM 200 series of Medium BARRIER SCHOTTKY DIODEs are metal semiconductor junction devices that have a typical short reverse recovery time. This allows their use at high microwave frequencies when the performance of the n-TYPE may be reduced. The forward I-V of SCHOTTKY DIODEs is determined by the junction metal used. For every different metal selection there is a different forward voltage characteristic or “BARRIER Height”. These devices are best suited for applications through 26 GHz.

Features
• Multi-Junction Chips
• Low 1/F Noise
• Small Junction Capacitance

Applications
  Medium BARRIER SCHOTTKY Mixer DIODEs are ideally suited for use in mixers, doublers and modulators.

Description : SCHOTTKY BARRIER DIODEs For Mixers and Detectors

DESCRIPTION
SCHOTTKY BARRIER devices are currently available in single beamlead, dual “T”, ring quad and bridge quad configurations. Devices are available in monolithic form for hybrid applications as well as in hermetic or non-hermetic packages. Monolithic devices are recommended for highest frequency, broadband designs. The beamlead design eliminates the problems associated with wire bonding very small junction devices thus improving reliability and performance in MIC applications. Our in house epitaxy process capability insures repeatability for lowest conversion loss through Ku Band. A broad range of unique metallization schemes produce Microsemi’s complete line of BARRIER heights. DIODEs are currently available with BARRIER heights as low as 240 mV and up to 625 mV per junction. By optimizing epitaxy and metallization, these devices achieve the lowest RS-CJ products resulting in exceptional conversion loss performance. “High Rel” screening is available on packaged devices per your requirements.
This series of devices meets RoHS requirements per EU Directive 2002/95/EC.
