Modern mobile satellite communication systems provide bidirectional broadband network access for moving ground, maritime and airborne terminals. Applications enabled by mobile SatCom systems include broadband Internet access, video conferencing and data transmission. Currently such systems—commonly called SatCom on-the-move—are being introduced on a large scale all over the world for...

In the world of tactical military communications, small size, light weight and versatility are essential for all components required for each deployable system. Locus Microwave, now part of the Codan family, has added the UB61000-050 X-band 100 W Block Upconverter (BUC) in accordance with this effort. The UB61000-050 features...

Design and Simulation Software A new version of the LINC2 Pro RF and microwave design and simulation software suite has been released by ACS. LINC2 V2.72 includes many new enhancements and upgrades, including new circuit models and simulation methods. Included among the many new enhancements are variable parameter sweeps,...

Components 14 to 18 GHz Bandpass Filter Model A65-MH004 is a 14 to 18 GHz bandpass filter. This filter has a 1 dB maximum insertion loss, 2:1 maximum VSWR, 10 W maximum operating power, and a stop band of -70 dB minimum from 0 to 11,900 MHz and 21...

E-GSM Diplexer Reactel part number 2DP-EGSM-900 is a diplexer for the E-GSM Band. This unit features passbands of 880 to 915 and 925 to 960 MHz with an in-band insertion loss of less than 1.2 dB. With 40 dB of isolation and minimum handling capability of 20 W, this...

High Gain MMICs The AE314 and AE312 are GaAs E-PHEMT MMICs with superior distortion characteristics aimed at the FTTx, CATV and broadcasting markets. The AE314 is a cascade amplifier with a typical gain of 22 dB. DC to 1 GHz, or DC to 2 GHz matching application is provided...

Detecting and Classifying Low Probability of Intercept Radar; Second Edition Phillip E. Pace This comprehensive book presents Low Probability of Intercept (LPI) radar design essentials, including ambiguity analysis of LPI waveforms, FMCW radar, and phase-shift and frequency-shift keying techniques. Moreover, it details new OTHR modulation schemes, noise radar and...

A novel stop-band frequency selective surface (FSS) is presented. By adding four narrow branches to conventional square-loop FSS, the proposed FSS can achieve a good frequency stability for different oblique angles and a high frequency selective ability. An equivalent circuit model is used to analyze its transmission property. Due...

Enhancement-mode PHEMTs significantly extend the usefulness of GaAs RFICs for general-purpose RF component designs. To demonstrate the technology’s benefits, this article demonstrates a 2 to 3 GHz GaAs PHEMT RF pulse modulator operating off a single, positive supply voltage, switched by a TTL-level logic signal. Active gate bias networks,...
