Phase 2 SBIR
A high power hopping filter assembly is proposed which will filter transmit and receive signals for up to eight SINCGARs radios. A multi-coupler is used so that a single antenna is used for the eight radios. This assembly is designed to use eight frequency hopped filters in the SINCGARS frequency band which will effectively filter up to 50 watts...
Phase 1 SBIR
This SBIR analyzes approaches for high power VHF hopping filters in which eight filters are used in a multi-coupler configuration so that a single antenna can provide signals to eight SINCGARS radios. Three approaches were studied: 1) a filter with series connected diodes, 2) a filter with shunt connected diodes and 3) a combline filter. A serie...
Phase 1 SBIR
Design proposed for reducing SINCGARS co-site interferers. Design uses 8 high-Q 5-zero notch filters with unique design techniques for very high Q. It uses 8 bandpass filters covering 1/8th the band for fast interferer acquisition. Once an interferer is recognized using log detectors and a microprocessor, the notch filter is tuned to the inte...
Phase 1 SBIR
Design techniques for a low loss 30 channel multiplexer are proposed. The Navy has a requirement for such a multiplexer in the 30 - 88 MHz frequency band for use in eliminating interfering signals in the receiver passband. Design approaches including L-C filters and combline filters are considered. Use of L-C filters will not meet the loss re...
Phase 1 SBIR
This is a study for the development of a diplexer for Navy Bouy application. Approaches to the diplexer are a receive band-pass and a transmit band-stop filter with a diplexing circuit. These are designed using lumped components or transmission lines. Preliminary analysis shows that for the transmit filter, a transmission line band-stop filte...
