mmWave PolyStrata(R) High Power Compact Transceiver, Phase I

Completed Technology Project

Project Introduction

In response to NASA SBIR Topic S1.02 on Microwave Technologies for Remote Sensing, Nuvotronics is pleased to propose a Phase I program focused on delivering an Ultra-compact W-Band High Power Transceiver. Our proposed plan is to take advantage of our PolyStrata ultra-low loss micro-coax transmission lines, high power high efficiency GaN power amplifier and Low Noise Amplifiers to provide a transceiver with over 10 Watts of CW RF power and with less than 6dB of received Noise Figure. The integrated PolyStrata micro-coax assemblies allow for a paradigm shift in design and manufacturing of advanced microwave and millimeter wave components supported by ultra-low loss transmission lines (0.03 dB/mm at 94 GHz), ultra-wideband (no cut-off), very high isolation (>80 dB) and no dispersion. This together with the highest functional density, integrated thermal management, scalability in power handling and frequency of operation enable novel architectures to be built in which the usual performance tradeoffs would no longer be necessary. In recent years, Nuvotronics has demonstrated multiple high power SSPAs from 30 GHz to 240 GHz, enabling mmW components using the disruptive PolyStrata micro-coax technology. Our architecture will also offer excellent thermal management using the PolyStrata bulk copper thermal conductivity of 400W/mK and the 3D RF backplane routing, which allow heat sink integrated directly under the MMICs for efficient heat spreading.
