Director of Active Microwave Circuits

 
 

Isotropic Systems is seeking world class candidates to join a fast-paced, proven team working on cutting edge technology in a successful startup company that brings significant opportunity for the right candidate. 

We are pioneering the introduction of innovative and disruptive low-profile multiple-beam satellite communications terminals for mobile and fixed applications. These highly integrated terminal systems combine elements of new advances in microwave lens optics, phased array antenna technology, and dynamic beam pointing control systems using analog and/or digital signal processing. Our terminal designs operate as fully electronic beam steering systems. Our IP has applications across a wide range of market sectors including: aeronautical, land mobile, maritime, and 5G, providing broadband, multi-beam, two-way communications with dynamic tracking of geostationary and non-geostationary satellites or terrestrial nodes.

Opportunity:

Isotropic is seeking an experienced Director of Active Microwave Circuits to manage the design and implementation of the active antenna subsystems of its mobile and fixed tracking antenna terminals, including the specification, design, analysis, and implementation of the transceiver architecture, signal processing, amplification and mixing stages, signal distribution and combination, COTS and custom MMIC specification and development, and integration of the selected circuits into a cost- and power-effective product. The position reports to the Senior Vice President of Engineering. Responsibilities will include designing and simulating beamforming circuit networks, evaluating MMIC technologies, processes, and vendors, designing and testing prototype RF-PCBs, and design for high volume and low-cost manufacturing. The role will also be involved in customer and vendor interactions. The candidate should have a proven track record of microwave circuit design experience in Ku-band and K/Ka-band.

This role will be responsible for all aspects of processing the signals within the satellite antenna terminal with emphasis on power consumption, noise figure and system noise temperature, total output power and antenna EIRP. The Active Microwave Circuits team will work closely with the other technical teams to design, implement, and produce a complete SATCOM terminal. Specifically, the Active Microwave Circuits team will interface with individual antennas, filters, and array layouts developed by the Passive Microwave Circuits team and will work closely with the Terminal Management team to ensure that the control and calibration systems built into the chips and circuitry can properly interact with the control hardware and software. Heat dissipation of the relevant ICs will be managed by coordination with the mechanical engineering team, as will the packaging and environmental considerations and mitigations. With Systems and Passive Microwave Engineering, the Director of Active Microwave Engineering is responsible for maintaining product noise, power, and link budgets.

Of particular importance is the candidate’s appreciation of and proven performance history for high-efficiency and cost-conscious microwave circuit design, simulation and testing. The selection of microwave components that maximize antenna feed network efficiency and provide the multiple-beam coverage over wide fields of view while minimizing costs for new products that are intended to be low cost disruptors into the Satcom markets is critically important. The successful candidate will have a good understanding of phased array beamforming networks with passive and integrated components, both analog and digital. The candidate will be expected to contribute to the design, development, and implementation of module- and terminal-level calibration processes and procedures in prototype and production. Experience in modeling circuit layouts including tolerance information and transitioning the designs to PCB and IC implementations is highly important. Understanding the selection of PCB materials and the cost and performance trades available from different manufacturers, vendors, and material grades is key.

Background in MMIC design and specification is critical to successful completion of our product goals. A strong understanding of the relative performance, cost, and capability trades available between foundries, processes, and implementation methods is necessary.

The Director of Active Microwave Circuits, along with the other Engineering Directors, will be jointly responsible to the SVP Engineering for ensuring that the product vision is realized through excellence in execution such that product lifetime quality metrics, manufacturable cost and performance goals are all met, in programs that are delivered within the project budget and on schedule.

The candidate should have a good understanding of design for manufacturability and cost-effective designs for a wide range of applications from high end aeronautical to low cost consumer broadband terminals.

A strong background in overall communication systems architecture is essential to be able to organize and oversee a multi-disciplinary flow-down of functional subsystem requirements to individual components, MMICs, and circuits. Experience with design, control, calibration, pointing and tracking, and productization of electrically-steered communication terminals is a strong qualifying factor.

The successful candidate will have demonstrated experience in leading a team in the development of active antennas, with strong managerial and technical capability. The Director of Active Microwave Circuits is expected to bring a high degree of creativity and problem-solving capability to search outside the box for new solutions to questions in the design, implementation, and operation of a cost-effective Satcom terminal. In addition, technical leadership is expected in the areas of analysis of complex Antenna systems for all-electronic antenna systems and motion-controlled stabilized platforms, and monitoring and maintaining trends of performance across multiple product lines and customer development projects.

The Director of Active Microwave Circuits will act as an individual contributor towards the development of the terminal, and will also be required to build and manage the daily activities of a world-class product development team including electrical engineering, embedded systems, control systems engineering, PCB design and layout, firmware development, and software development skillsets in-step with product development activities that dovetail into the overall company objectives.
