“Be Very Careful” By Tom Kurian, President & CEO, Renaissance Electronics Corp.
“Be very careful” — a mother’s passing comment to her kids as they head outside. The words describe a way of living that is precise, accurate, and deliberate. It involves both forethought and a heightened sense of awareness. I wrote this to build awareness in companies involved in manufacturing and trading products for defense and Sat-Com programs.
A significant number of rooftop antenna sites owned primarily by wireless carriers exceed FCC public and occupational exposure limits, make it impossible for workers to avoid standing in front of antennas, and are inadequately posted with warnings and barriers. Read More...

New 6-Bit Digital Phase Shifter The MAPS-011008 is a digital phase shifter for C-band radar applications. It facilitates easy implementation in communication antennas, phased array radars, and weather radars, and was designed specifically for 5.0 to 6.0 GHz applications. M/A-Com Technology Solutions
DC Block Power Dividers & Combiners Series DCB-1020 is an in phase power divider/combiner with high isolation, small size and superior performance in a single package. These units utilize microstrip construction with blocking capacitors on all ports except those that are intended to pass DC. RLC Electronics
Surface Mount Bandpass Filter CBP-1307C+ is a ceramic-coaxial-resonator based bandpass filter in a shielded package fabricated using SMT technology. Frequency range is from 1215 to 1400 MHz. It offers outstanding close in rejection, low insertion loss and high power handling. Mini-Circuits
CW Immune, ERDLVA Model ERDLVA-218-CW-LPD-100 is a CW immune, extended range detector logarithmic video amplifier (ERDLVA) designed for ultra low DC power consumption. It operates over the 2.0 to 18.0 GHz frequency range and offers a log slope of 77mV/dB into a 100 ohm video load. PMI
UHF Input Test Coupler The company provides a UHF input test coupler for one of the payloads in the newly launched Mobile User Objective System (MUOS-1) satellite. Insertion loss is 0.12 dB max.; coupling is 30 dB typ.; directivity is 15 dB; and VSWR is 1.25:1. Delta Microwave
High Power Amplifier Module Model BBM5K8CKT is a 2500 to 6000 MHz amplifier guaranteed to deliver 100W output power and related RF performance under all specified temperature and environmental conditions. It is suitable for broadband jamming and high power linear applications in the S/C bands. EMPower RF Systems

•Directivity and VSWR Measurements
Return loss and VSWR measurements are complicated by the finite performance of the directional device used to measure the reflected power. The only accurate and convenient way to make return loss measurements is with a well matched high directivity directional coupler or bridge. Marki Microwave
