RF/Millimeter Wave
Research and Development
Teledyne Scientific Company’s millimeter wave electronics focus on a new and promising architecture called Millimeter Wave Beam Circuits (MBC). The MBC approach borrows heavily from previously advanced quasi-optics concepts, which recognized and exploited the inherent advantages of free-space power combining as compared to traditional, planar power combining methods.

Intrinsically three-dimensional, the MBC approach relies on tunable, TEM waveguide structures enabled by engineered two and three dimensionsional metal-dielectric structures called photonic bandgap materials. A wide variety of high power, high performance millimeter wave applications of MBC are currently being studied at Teledyne Scientific Company. These include:
  • Low cost, high performance Ka-band electronically scanned antenna array
  • Extremely compact and efficient solid-state W-band source capable of achieving multi-watt output
  • Intelligent RF power amplifier, achieves >10W power and self-tunes from 25 to 45 GHz
The work in this area is enhanced through Teledyne Scientific Company's expertise in developing advanced MMIC (monolithic microwave integrated circuit) devices. In-house capabilities include pseudomorphic high electron mobility transistor (PHEMT) processing. Our GaAs PHEMT MMIC process, which is ISO 9001:2008 certified, makes use of electron beam lithography-defined gates with widths as small as 0.1┬Ám. Teledyne Scientific Company can reliably produce high performance circuits that operate up to W-band (to 110 GHz) for low noise (LNA) and power (PA) circuits.
