Millimeter Wave Subassemblies Enable Next-Generation R&D Projects By Renaissance Electronics Corp.
This article describes two high profile millimeter wave projects. The first project involves one of just two particle accelerators in the world to transmit course correction high-speed signals ahead of the speed of light. The second is a Department of Homeland Security project that involves the development of advanced phased array radar systems for the detection of suicide bombers at stand-off distances.
Spotlight On Millimeter-Wave Technology
44-GHz Millimeter-Wave Amplifier API Technologies’ new MMW amplifier (model BXHF1075) offers both high efficiency and extreme stability with 13 dB of return loss, all while generating 30 dB of gain and +17 dBm of output power off a +15 volt supply. It also incorporates an internal voltage regulator to accommodate either +12 volts or +15 volts.
43- To 46-GHz GaN Power Amplifier This power amplifier operates in the 43-46 GHz frequency range and is ideal for applications involving military satcom, terminal amplifiers, and phased-array radar applications. It has a linear gain of 20 dB (typ) and a 38.5 dBm (typ) power saturation. Additional information can be found on the available datasheet.
Millimeter-Wave Directional Couplers Krytar offers millimeter-wave directional couplers in the 10 to 67 GHz range. Coupling (with respect to output) is 16 ± 1.1 dB and frequency sensitivity is ± 2.0 dB. These couplers also feature directivity of 7.25 dB. maximum VSWR (any port), 2.0. insertion loss at < 1.95 dB. maximum, and a power rating (input) of 20 W average, 3 KW peak.
High-Power Amplifiers Ducommun’s line of high power amplifiers operate in the 18 to 98 GHz frequency range for high output power applications. They feature a wide operational temperature range, up to full waveguide bandwidth, and are compact and lightweight. Outline drawings and specifications can be found on the available datasheet.
Direct Connect Solution For MM-Wave IMD Measurements OML introduces the industry’s first direct connect solution for millimeter-wave intermodulation distortion (IMD) measurements. Fitted to characterize millimeter-wave devices for S-parameters and gain compression, IMD is an industry standard technique revealing the linearity of an amplifier using a two-tone measurement.
Ka-Band Power Amplifier The MSC2931P3540 is a power amplifier supplying a minimum of 10 W of output power, at P1dB, at a base plate temperature range of 25°C for use in Ka Band SATCOM uplink applications. The power amplifier operates from 29.5 to 31.0 GHz with a maximum gain of 38 dB from a single +5V supply over a base plate temperature range of -55 °C to +70 °C.
The Anritsu MS4640A Vector Network Analyzer offers a new level of performance for device modeling engineers struggling to accurately and reliably characterize their devices, for R&D engineers pushing the last fraction of a dB out of their state-of-the-art designs, and for the manufacturing engineer trying to maximize throughput without sacrificing accuracy.
Mini-SMT thin film resistors offer maximum benefits in ohmic value ranges from .5 W through 500 MW. T.C.R.'s to ±5ppm/°C - and absolute tolerances to 0.05 percent. Available in 0505, 0805 and 1206 sizes, these resistors provide proven thin film performance in a surface mount solderable style.
