RF Architect

Department Description

Cambium Networks develops Point to MultiPoint and Point To Point RF solutions in both unlicensed and licensed bands. Customers include tier 2 and 3 telephony operators, wireless internet service providers, enterprises such as utilities, and federal, state, and local governments. Point to MultiPoint technologies include both proprietary Canopy and standards-based protocols.

Scope of Responsibilities & Position Expectations

Hardware team is in search of candidates responsible for leading the identification and development of the next generation of integrated antenna/radio systems used in Massive MIMO and MuMIMO systems. Your expertise will lead us in the design, specifications, and development of point-to point, and point to multi-point technologies for outdoor, split-mount, and indoor radio systems for both sub 6 and mmwave (>60 GHz) frequencies.

· You will lead the analysis, design, and specification of the overall radio and sub-systems required for developing wireless platforms.

· You will work closely with hardware engineers to develop the requirement specification documents for radio sub-systems such transceivers, RFICs, and IF and Baseband assemblies, and work closely with software and firmware (FPGA developers) engineers to generate software and firmware requirement documents.

· You will collaborate closely with ATE engineers to develop radio level test strategies and factory implementations.

· Your previous experience will help you devise radio calibration strategy, design calibration algorithms in support of factory room temperature test and calibration.

· As the leader, you will conduct Preliminary Design and Critical Design Reviews during development cycle.

· You will work closely with the team to specify design and performance requirements of vendor supplied measurement systems and sub-assemblies.

· You will lead the performance system cascade analysis considering linearity, phase noise, gain, group delay, receiver sensitivity, and all other channel impairments and spurious response.
