APITech specializes in offering fully customized, high performance and high reliability silicon microwave diodes for space, satellite and mega constellation applications. Our PIN, LIM, Step Recovery & Tuning Varactor microwave diodes provide broadband performance from 1 MHz to 20 GHz in ceramic packages ideal for switching, attenuator and control applications.
Our years of robust heritage coupled with our skilled design and production staff provides OEM companies with high quality, custom microwave semiconductor products as well as higher level assemblies. Manufactured in a Class H & K facility and tested to MIL-STD-883 and MIL-STD-202, API’s microwave diodes for space are amongst the most robust and reliable on the market.
These diodes find application in high efficiency multiplier and up/down converter applications and for comb generators.
Tuning Varactor Diodes are ideally suited for frequency tuning applications up to 20 GHz. These devices are designed for use in solid state electronic tuning of transistor, Gunn and IMPATT oscillators. They may also be used in phase shifters up and down converters and low order multipliers.
The ML 4600 Series of PIN and NIP diodes are designed for control applications such as RF switching limiting, duplexing, phase shifting, modulation and pulse forming.
ML 4650 high breakdown PIN diodes exhibit low thermal resistance and are designed for use in high power switches, receiver protectors are phase shifters from 0.1 to 18 GHz.
These PIN devices are intended for microstrip or stripline control circuits as well as for direct replacements for existing non-hermetic epoxy encapsulated devices. They can function as power switches, limiters, phase-shifters, attenuators and duplexers.
APITech’s series of passivated PIN diode chips have an optimally tailored profile and sputtered gold metallisation. Our total in-house capabilities allows or broad spectrum of epitaxial resistivities and thickness for specific design requirements.
The reduced series resistance makes the low capacitance versions ideally suited to high frequency operations.
The ML 4200 Series is a range or oxide passivated silicon mesa diodes designed for limiter applications, especially those requiring low turn-on.
Frequency Multiplier Diodes, Tuning Varactor Diodes, and PIN Diodes are designed for control applications.
Through our state-of-the-art, MIL-PRF-38534 Class K certified facilities in Marlborough, MA, USA and Great Yarmouth, United Kingdom, APITech can satisfy the most stringent quality assurance requirements demanded by the world’s tier one space contractors.
Our facilities offer a wide range of in-house mechanical and environmental screening and auto-electrical testing for element evaluation as well as completed product qualification. APITech has an independently managed, ISO 17025 accredited test facility providing full environmental testing against MIL-STD-883 and MIL-STD-202 test methods.
