RF, mm-wave & MMIC products showcased at IMS2015

“We are proud to launch these highly differentiated 13 solutions, which cater to the shifting needs of our customer base, as well as the industry’s growth forecasts in the defence, communications, instrumentation, industrial, and aerospace markets,” said Norm Hildreth, vice president and general manager of Microsemi’s Discrete Products Group. “Microsemi offers RF, microwave, and mm-wave antenna to bits solutions with a progressive emphasis on high performance semiconductor (CMOS, SiGe, GaAs, GaN and InP) and packaging technologies. This has allowed us to work continuously with industry leaders in our target markets to solve complex engineering problems at the discrete, RFIC, MMIC, module and subsystem levels.”

During the IMS2015 exhibition, the new devices, as well as other industry-leading products from Microsemi, will be on display for engineers, system architects and researchers interested in technologies that would differentiate their new designs.

Microsemi’s booth, 1348, will showcase products areas where attendees can interact with Microsemi technical experts and discuss some of the company’s most innovative products and system solutions.

Products to be showcased include:

GaN HEMT RF power transistors

Microsemi’s expanded family of RF power transistors based on GaN High Electron Mobility Transistor (HEMT) on SiC technology will feature five L & S-band RF power transistors rated between 150 and 800W. The 1012GN-800V, 1214GN-600VHE, 1214GN-400LV, 3135GN-280LV and 2425GN-150CW RF power transistors deliver outstanding performance in terms of size, weight, power and efficiency in a wide range of avionics, radar and Industrial, Scientific and Medical (ISM) applications.

Monolithic SPST PIN switch elements

Microsemi’s MPS4101-012S and MPS4102-013S are single-chip silicon monolithic series-shunt elements designed with minimal parasitic inductance to provide optimum insertion loss and isolation characteristics over the entire 50MHz to 40GHz frequency range. These products are suitable replacements for the conventional shunt mounted chip and series mounted beam lead PIN diode normally used in the manufacture of broadband microwave switches.

With less than 1.1dB insertion loss and isolation of 31dB at 26GHz, coupled with fast switching times of 5ns while handling 3W of continuous wave power, these devices suit wideband high linearity applications such as test equipment, electronic countermeasures, and electronic warfare. These products meet RoHS requirements per EU directive 2002/95/EC.

Broadband coaxial limiters

Microsemi’s GG77317-01 through GG77317-05 series of broadband coaxial limiters provide unprecedented CW power handling capability across the 10MHz to 2.5GHz, - to 4GHz and - to 6 GHz frequency bands. Capable of limiting 60, 70 and 100W of incident CW power, these broadband coaxial limiters are suitable for receiver protection in ECM, EW, radar and test equipment applications.

These coaxial limiters feature insertion losses as low as 0.3dB and maximum VSWR values of 1.4:1 over the 2 to 3GHz frequency range. All device variants provide 1,000W of peak RF power handling capability and typical recovery times between 1.5 and 2μs. Suitable for use in rugged environments, as well as RF and microwave laboratory applications, these PIN diode-based limiters feature SMA female connectors and are designed to meet or exceed the MIL-STD-883 environmental conditions without damage.

RF modules & subsystems

Microsemi’s L0618-50-T523 is a high power broadband GaN amplifier that delivers 100W of saturated output power over the 6 to 18GHz frequency range, and is offered in a compact 25.4x20.95x15.24cm rack mount configuration. Designed for land mobile electronic warfare applications, the L0618-50-T523 amplifier operates from -20 to +50°C baseplate temperature, and is provided with heat sinks and fans for cooling. The amplifier is fault-protected with over temperature and reverse power monitors, and operates from a +28 to +36VDC power supply.

About Ultimate Performance MMICs

Microsemi's portfolio of MMIC products spans the DC to 65GHz frequency range and targets a broad range of applications including those in electronic warfare, radars, test and measurement instrumentation, and microwave communications. The portfolio is based on high performance process technologies and comprises high power and low noise broadband amplifiers, amplifier modules, prescalers, attenuators and switches. Microsemi offers 17 distributed amplifier products. Microsemi's prescalers combine higher frequency operation, the flexibility to divide by a large number of ratios and excellent residual phase noise.
