AbstractThere is a need for low cost, spectrally efficient, miniature, rugged, telemetry transmitters for small missiles, rockets, projectiles, and micro-UAV’s. Current solutions are typically only suitable for large missile platforms and aircraft and are cost prohibitive for expendable munitions such as projectiles. M/A-COM, Inc. has developed new digital polar transmitter architectures (DTx) for use in cellular handsets. This break through technology reduces size, power consumption, and component count. This significantly reduces the size and cost of transmitter circuitry for the handset. The architecture provides digital phase up-conversion and digital RF amplitude modulation. In addition it allows for achieving power amplifier efficiencies similar to linear PA’s with constant envelop waveforms when presented with non-constant envelop waveforms. This technology development can be utilized to provide very low cost, miniature, rugged transmitter solutions for systems requiring a flexible embedded instrumentation solution. This paper reviews the system architecture, discusses the integrated circuits development, and provides possible applications.
