Transceivers & Converters |
Teledyne Microwave has developed a number of integrated converters used in
today’s modern systems
Teledyne Microwave offers a full range of integrated converters for many
applications including Satcom and MilComs.
General construction consists of a RF/Microwave circuit using microwave modules
and either a single or multiple printed circuit boards for control and power
conditioning. The microwave modules are produced in house, on thin film circuits
which are then wire bonded together to make a complete microwave chain. By using
a common module concept, design cycles and risk are very much reduced when
developing new designs for custom applications. With over 1,500 microwave
modules designed and available, most requirements are met using existing proven
module designs. The power and control circuit boards usually circle the main
microwave modules, as these circuits are more flexible in location, and are
therefore more specialized for any given frequency converter.

With experiences from UHF to 40 GHz we have a wide portfolio of circuit
architectures, configurations and functionality to meet many different platform
needs. A large part of our work when designing new converters is power
management and digital control and functionality. Over the years we have found
these criteria often more demanding than the microwave design itself. Experience
in isolating supply lines and designing the unit with utmost isolation between
adjacent circuits is critical to achieving the best design possible.
In general most of the converters we produce are custom designs based on
existing units and modules available. With the recent need to push frequencies
higher, Teledyne Microwave has developed a number of Ka-Band upconverters
specifically for the Military Satellite communications market. These converters
also include the option for a Solid State Power Amplifier (SSPA) with power
levels up to 15 W available. A range of down converters have also been
developed, in the K-Band, to support the platforms very low noise figure
requirements.

Critical to all converters designs is the consideration of the local Oscillator
circuit to maintain the phase noise and spurious specifications, which are often
system critical. In some cases this is supplied by the system, but in most cases
the converter is responsible for generation these signals internally. Teledyne
Microwave has the ability to design these circuits in house. From the very
complex dual loop frequency synthesizer to more simple phase locked loop
designs, our engineers have proven our ability to not only design these circuits
but also to manufacture them in a production environment.
Additional functionality is also common place in the design of the converter. A
list of common functionality requirements that we see and support is shown below
(note: this is not a complete list):
- Current Monitoring
- Digital Frequency Control
- Automatic Gain Control
- Temperature Compensation
- Battle Short
- Temperature Monitoring
- RF Log and Linear Power Monitors
- Output VSWR monitoring and automatic shut down
- Return Power Detect with shut down capability
- Front End Limiter
