Existing telemetry bands are heavily sought after by non-aerospace industries for personal communication and entertainment uses. This has reduced the already limited radio Frequency (RF) spectrum available for aeronautical telemetry. Improvement in the spectral efficiency of tactical telemetry signals is therefore critical. Developing a waveform agile telemetry transmitter in which waveform parameters can be reconfigured to make efficient use of the available spectrum is useful. To address this, IAI and its collaborators from Purdue University have been awarded a new contract entitled, “Dual S & C-Band Telemetry Transmitter System for Missile Testing.” A Waveform Agile Telemetry Transmitter (WATT) will be designed to support simultaneous dual-band S-C band operation (S-band, 2200-2400 MHz and C-band selectable between 4400-4950 MHz and 5091-5250 MHz). The proposed architecture will employ state of the art, highly integrated, wideband Monolithic Microwave Integrated Circuits (MMIC) and reconfigurable digital processor to achieve desired miniaturization and multi-band capability. A Xilinx Spartan-6Q Defense Grade FPGA will be used for improved security, power reduction and integration. Low power, wideband Phase Lock Loops (PLL) and I-Q modulators will manage the dual band RF up-conversion. Purdue University will develop the wideband RF power combiner and power amplifier that will simultaneously work in S-C bands. The low-risk, reconfigurable WATT module will be a 3-stack PCB design that conforms to the MDA’s volume requirement of 2 in. x 3 in. x 1 in.
