An X-band digital transmit module will be developed that is suitable for phased-array radar and communications applications. This proposed Phase II SBIR will combine our Phase-I X-band transmit module design with a DBF receiver that Applied Radar is developing through separate (non-SBIR) funding from AFRL. In addition, we will investigate the development of a synthesizer to provide a common LO sig ...

The future capabilities of sensors and instrumentation deployed in space will continue to increase, resulting in increasing amounts of collected data. To reach these higher speed data rates, increases to the overall system gain of the communication link will be required. A deterministic method to increase system gain of a RF communication link is to provide higher transmitted RF power. However, ...

An X-band interferometric radar (XBIR) system employing digital beamforming (DBF) is proposed to supplement the S-band multi-mission radar (MMR) phased array currently under development by Syracuse Research. This auxiliary X-band array will bolt onto theapproximate 1.5 x 2.0 meter MMR array and provide a precision tracking capability for fire control. The two radars will operate cooperatively in v ...

Hittite proposes to develop an ESA to greatly improve TT&C performance compared to current reflector antennas. The ESA will provide multiple (at least one TX and four RX) independent, simultaneous full-duplex beams over ± 180° azimuth and ± 90° elevation. In addition, the ESA will provide gain on demand, fast beam scanning/switching, quick response to surge loads, and low life-cycle cost. Th ...

"A multi-channel transmit array is to be developed for high-speed digital communications and radar applications. Digital beamforming (DBF) will be combined with direct digital synthesis (DDS) waveform generation to achieve a system capable of using bothwaveform diversity and spatial diversity. Multiple simultaneous transmit beams will be generated that may be configured and scanned digitally. Usin ...

In Phase I, Diversified Technologies, Inc. I proposes to design and demonstrate a new flexible, modular multi-phase buck regulator power supply for use in phased array radars. The proposed design is substantially more efficient and reliable than either thetransformer-coupled DC-DC converters or conventional buck regulators presently in use. Its use will reduce the converter's cooling requirements ...

Advanced wideband, large, multimode distributed phase array radars require T/R modules which are much smaller and lower in power than present components. Q-DOT proposes a staged X-band receiver block (XRB) development, beginning with the key analog to digital converter (ADC) and supporting circuits (T/H, demux). The proposed ADC directly samples the X-band, eliminating intermediate frequency (IF) ...

Advanced wideband, large, multimode distributed phase array radars require significantly improved T/R modules. Q-DOT proposes a staged X-band receiver block (XRB) chip development, beginning with the key analog to digital converter (ADC). Combined with key RF front end cells and integrated as a single-chip X-band receiver, the proposed X-band receiver block offers 10 to 20 dB dynamic range improve ...

TLC demonstrated a high performance remote Doppler Radar adjustable X-band to W-band transceiver chip that can perform well as a FMCW, super-heterodyne or pulse radar that meets space qualification specifications. This reconfigurable transceiver will serve as the basis for the precipitation & cloud measurement doppler radar system that will be developed, tested and delivered to NASA in this Phase ...

During Phase I, TLC will demonstrate and deliver a remote mixed-mode adjustable X-band to W-band transceiver chip that can perform well as a FMCW, super-heterodyne or pulse radar that meets space qualification specifications. This reconfigurable transceiver will serve as the basis for the precipitation & cloud measurement doppler radar system that will be developed, tested and delivered to NASA i ...
