Kratos General Microwave

Digitally Tuned Oscillators (DTO)

Kratos General Microwave offers a line of DTOs covering the 2-18 GHz frequency range based upon its catalog line of broadband VCOs. The DTO provides the desired output frequency in response to a digital control signal. A block diagram of the DTO is shown in Fig. 1. By appropriate design of the electronic circuitry, settling times of less than 300 nanoseconds are achieved. To obtain a frequency accuracy of the order of ±1%, including the effects of temperature, a proportionally controlled heater is required for the VCO and the electronic circuitry is temperature-compensated. A latch mode is provided as a standard feature.

Multi-Band Frequency Locked Oscillator (FLO)

Kratos General Microwave has developed a new product line of Multi-Band Frequency Locked Oscillators (FLO). This product line is an enhancement to our free running Digitally Tuned Oscillator (DTO) products. This FLO combines the high speed of DTO with the high accuracy and long-term stability of a frequency locked source. The key specification feature of the FLO is a timing speed of less than 1μsec to settle within 1 MHz of the desired frequency.

SIMULATOR AND TEST SYSTEMS APPLICATIONS

The FLO was specifically designed for test systems and simulator applications. It is a low cost replacement for high cost direct synthesizers, in applications that the frequency setting time of 1 μsec is meeting the system requirements.    

Voltage Controlled Oscillators (VCO)

Kratos General Microwave has developed a family of high-speed, miniaturized VCOs covering the 2-6 GHz frequency range. These VCOs have been utilized in airborne EW applications, as well as in ground-based simulators.

Microwave Synthesizers, RF Synthesizer

Kratos General Microwave (KGM) has developed a broad line of General Purpose RF and Microwave Synthesizers to be used in various applications. KGM has developed a line of high performance, broadband Fast Indirect Synthesizers (FIS) to provide a cost-effective solution to the requirements of new systems. Its high speed (as fast as 1 µsec) provides an economical alternative to direct synthesizers for manyapplications. Because of its low phase noise, it is an excellent alternate to the much slower and generally less reliable YIG-based rf synthesizer.

To provide optimum solutions for different requirements, Kratos General Microwave has developed a variety of Fast Indirect Synthesizers (FIS) with different parameter trade-offs: The standard FIS line for fastest tuning speed, the low phase noise line for ELINT applications and the compact FIS line for airborne small size applications. Some of the FIS rf microwave synthesizers can be configured (optionally) to operate as a dual mode source. In the synthesizer mode and in the high speed (1 µsec) DTO mode with modulation capability.
