ANTENNAS Extreme Interference Antenna The 26000 series antenna is designed for interference levels in the Global Positioning System (GPS) band and offers high, narrowband filtering that eliminates the fundamental interference at lower frequencies. The antenna has a high front-to-back ratio null to attenuate the narrowband third-order harmonic. A tilt...

AMPLIFIERS 2 W X-band Amplifiers These 2 W power amplifiers are designed for radar and phased-array applications and offer coverage over standard X-band frequencies with high dependability and reliability. All units can be customized to meet exact gain and frequency requirements. JCA Technology Inc., Camarillo, CA (805) 445-9888. Dual-band...

INTEGRATED CIRCUITS Nonvolatile FPGA The model RH1020 nonvolatile, radiation-hardened field-programmable gate array (FPGA) (part of the company’s RadHard product line) offers short time-to-launch in the commercial satellite market. The model is based on the company’s antifuse architecture that survives exposure to a maximum total dose of 300 KRAD (Si)...

SOURCES High Frequency PLL The model PLL800-5800 high frequency phase-locked loop (PLL) operates from 5700 to 5900 MHz with a supply voltage of +5 V and step size of 500 kHz (typ). Additional features include a phase noise of –105 dBc/Hz (typ) at 100 kHz offset, typical output power...

TEST EQUIPMENT Mechanically Refrigerated Thermal Platform This mechanically refrigerated thermal platform (MRTP) relies upon a closed-loop mechanical refrigerated cooling system that eliminates the need for expectorant-based, nonreusable refrigerants such as liquid nitrogen and liquid carbon dioxide. The unit utilizes a quiet and efficient mechanical refrigeration system that recirculates the...

SUBSYSTEMS C-band Frequency Converter Modules The MTS4000 series synthesized frequency converters can be used in a variety of applications such as redundant or simultaneous up/downconversion in a single 19" 1RU converter assembly. The modules measure 5.00" x 11.00" x 1.44" and cover both the standard and extended satellite bands...

SOFTWARE CDMA/PCS Library This library allows engineers to design, simulate and test end-to-end CDMA or PCS communication systems and is used with the company’s SystemView software for Windows ’95/NT. The library supports rate sets 1 and 2 as defined in the IS-95-A, IS-97-A, IS-98-A and J-STD-008 specifications. Provisions have...

MATERIALS Low Frequency Absorbers The RFSW series low frequency absorbers are thin magnetic elastomeric sheets supplied with a pressure-sensitive adhesive for quick installation to an RF cover or circuit. The absorbers can be supplied in flat sheets or die cut to individual pieces to reduce the cost of production...

News From Washington ATC Beacon Interrogator Competition Begins Next Phase The Lockheed Martin/Northrop Grumman team has been selected by the Federal Aviation Administration (FAA) as one of two contractors to demonstrate and test a new civilian secondary radar system as part of the FAA’s Air Traffic Control Beacon Interrogator...
