RF and Microwave System and Circuit Analysis
The team at Clear Crest Wireless brings together vast experience in the domain of system and circuit analysis, and in particular RF amplifier linearization and design, antenna design, thermal management and mechanical design :
System Analysis and Design
New concept block and level analysis, Gain and Power, noise, IP3 and P1dB, and spectral analysis. By doing so, one may choose the right components to achieve overall required system parameters. Key to accurate system design is that simulations are performed using mathematically created real world signal formats such as WCDMA, LTE, etc. This ensures accurate results after circuit creation and introduction to manufacturing.
Circuit Analysis and Design
The use of the right techniques and components is the "black art" of RF and microwave circuit design, where everything is critical: the choice of the right devices, circuit multi-layer construction, matching design, device attachment to carriers, adequate thermal margins, these are among a myriad other choices a designer must make. Prior experience, correct simulation and manufacturing process know-how from the start are the only way to ensure proper manufacturing yield and product quality. Capabilities include LDMOS, GaN and GaAs based amplifier designs, mW to High Power, high PAR ratios, Doherty High efficiency designs.
All modern communications systems employ high Peak to Average signals such as OFDM for maximum spectral efficiency. Amplifier linearization is essential for system efficiency and overall transmission quality. The choice of Analog or Digital Pre-distortion, or a mix of the two, is a key element of any successful system design. Techniques include the effective treatment of both memory less systems and those that include and reactive and thermal effects.
Advanced filter design is essential for all telecom installations where the proper frequency management and distribution of signals must be achieved with challenging multi-band, designs that operate in extreme environments. Our multi-cavity resonator designs offer industry leading size weight and performance advantages
Antenna Analysis and Design
Wireless system designs require advanced antennas that are compact, multi-band, and offer advanced features such as Remote Electrical Tilt, Azimuth adjustment, and in the future beamwidth, control. Increasingly, Active Arrays are being considered, along with antennas with Integrated Remote Radio Heads. The right design choices are crucial for the development of advanced antenna systems, as is the choice of the correct material for the avoidance of issues such as passive intermodulation in future production.
Thermal Analysis and Design
Thermal considerations should be a high priority in advanced RF system development. A concept simply cannot proceed until the thermal and reliability implications are carefully examined. With an advanced thermal simulation and design, the right components can be chosen that will offer the ultimate system reliability and field performance
Advanced mechanical engineering is an essential part any development and launch of products for the telecom industry. It is essential to incorporate size , weight and thermal management in any new design along with proper material science to end up with structurally sound and aesthetic designs
