Amplifiers, MMICs, Devices & TWT Assemblies

ENGIN-IC, located in Plano, Texas and San Diego, California, provides differentiation for companies looking for advanced MMIC and module solutions. The founders of the company bring over a century of Microwave product design experience from MMICs to complex RF subsystems primarily in the Defense, Hi-Rel, and Telecommunication markets. The company has an excellent understanding of microwave technology and designer requirements for advanced RF products.

ENGIN-IC provides industry leading technology and responsive customer service that can provide a competitive edge. Our extensive technical knowledge of MMIC design, coupled with our understanding of Microwave subsystem requirements, bring performance differentiation to our products.

The RF input to the Solid-state power amplifier, is pre-amplified and split into several parallel symmetric branches. Each branch includes a power amplifier section (PA). This distributed design of the microwave SSPA results in built in redundancy and graceful degradation of output power should any individual PA section fail. Each branch includes a current sense alarm indication which is monitored and fed to the RF SSPA controller. The amplified outputs of all the symmetric branches are summed up in a passive combing network which routes the resultant high power to the output of the RF SSPA.

A compact and highly efficient switching Power Supply Unit (PSU) is built into the solid state power amplifier. This state-of-the-art PSU design ensures that any contribution of phase noise and spurious signals are significantly reduced at the RF output. The microwave SSPA control section includes a Modulator which switches the DC lines of the individual PA sections On/Off to achieve the required Pulse Width, Pulse Repetition Interval and Duty Cycle. The SSPA Monitoring section includes Built-in-Test capability which receives indications from critical internal subassemblies, including the PA sections, thereby constantly monitoring the condition of the microwave SSPA. Most of our solid state power amplifier designs are custom, deriving from Customer specifications because of the differing requirements for specific applications such as Airborne Radars and Missile Seekers. There are, however, many applications which can be served by more generic solid state power amplifiers as summarized in the below table. They are offered as Special Catalog SSPAs and intended to provide the user with a proven, cost effective solution rather than a new design.
