Pentek announced the newest member of its popular Jade® family of high-speed data converter XMC FPGA modules: the 2-channel Jade Model 71865, a 200 MHz 16-bit A/D channelizer with 762 narrowband digital down converters (DDCs) and 4 wideband DDCs, based on the Xilinx Kintex UltraScale FPGA. The Model 71865 is an economical and energy efficient, complete software radio receiver solution for commercial, military and government high-channel count applications. The Model 71865 functions include two A/D acquisition IP modules for simplifying data capture and transfer. Each acquisition IP module contains a powerful controller for all data clocking, triggering and synchronization functions. From each of the two acquisition modules, A/D sample data flows into identical IP modules consisting of banks of wideband and narrowband DDCs. Finally, data is delivered to four DMA controllers linked to the PCIe Gen.3 x8 interface for transfer to a signal processor.

Although its focus is supporting Murata’s semiconductor needs, pSemi (formerly Peregrine Semiconductor) announced several new catalog products, for the first time tapping into semiconductor processes other than their historic allegiance to the UltraCMOS® SOI process.

For 5G massive MIMO base stations, pSemi introduced four switch+LNA modules integrating UltraCMOS switches with GaAs and silicon LNAs. Covering the 2.3 to 2.7 GHz and 3.3 to 3.8 GHz bands, the switch+LNA modules are offered in single- and dual-channel configurations. The designs comprise an input receive protection switch followed by a two-stage LNA — first stage GaAs and second stage UltraCMOS — with a bypass switch around the second stage. pSemi says the modules use 25 percent lower power and are 60 percent smaller than competitive GaAs solutions.

For millimeter wave applications, pSemi introduced a 9 kHz to 50 GHz DSA. In a flip-chip die format to maximize performance, the 6-bit design provides 31.5 dB dynamic range. pSemi also introduced four “value” DSAs covering various bands from 9 kHz to 6 GHz: 50 Ω 2-, 5- and 7-bit versions and a 75 Ω 6-bit DSA. Jim Cable, CTO, said pSemi invented the single-chip DSA in 2004 and these additions provide good performance at an attractive price.

Qorvo announced seven products in conjunction with IMS: five products for sub-6 GHz 5G infrastructure and two GaN front-end modules (FEM) for X-Band phased array radar.

The infrastructure line-up includes two GaN Doherty power amplifiers that provide 5 W average power from 3.4 to 3.6 GHz and 3 W average from 4.4 to 5 GHz. A companion wideband driver amplifier, matched to 50 Ω and fabricated with Qorvo’s enhancement PHEMT process, covers 1.8 to 5 GHz and provides 22 dBm output power at 1 dB compression. Two switch-LNA FEMs for base station receivers cover 1.8 to 4.2 GHz, with 1.45 dB noise figure, and 3.8 to 5 GHz, with 1.1 dB noise figure.

The X-Band FEMs integrate a T/R switch with LNA and power amplifier, all fabricated with Qorvo’s GaN process. The two designs cover 8.5 to 10.5 GHz and 9 to 10.5 GHz. The broader bandwidth design delivers 35 dBm saturated output power with 32 percent power-added efficiency and has 2.2 dB noise figure, while the narrower bandwidth FEM delivers slightly more power and efficiency — 36 dBm saturated and 38 percent — and 2.7 dB noise figure. Both are classified as EAR99, allowing them to be exported for most international programs.

They are offered with or without copper cladding.

SignalCoreSignalCore was featuring the SC5318A that is a C to K broadband single-stage downconverter, converting frequencies from 6 GHz to 26.5 GHz down to 50 MHz to 3 GHz. The LO frequency range is from 6 to 26.5 GHz with an input LO range from 6 to 14 GHz. An internal frequency doubler multiplies the input LO range up to 26.5 GHz. This module also features an internal 26.5 GHz synthesized LO, RF preamplifer, and variable gain control making it a compact standalone downconverter module. With the option for an external LO signal, the SC5318A may be configured for SISO applications or paired together for MIMO applications such as ground-based satellite communications, point-to-point radio, and test instrument systems. The SC5318A can be combined with SignalCore's SC5308A to form a broadband 100 kHz to 26.5 GHz downconverter. These high-performance converter modules are compact, rugged, and built for simple integration into larger systems.

Synthesizer are made by combining YIG filter tuning for course adjustments and optical transversal filter tuning for find adjustments. Phase noise performance for X-Band is -110 dBc/Hz for 1 kHz offset and -136 dBc/Hz at 10 kHz offset.   K-Band phase noise performance is -102 dBc/Hz for 1 kHz offset and -127 dBc/Hz at 10 kHz offset.

WIN Semiconductors announced two process extensions at IMS: the NP45-11 0.45 µm GaN process for wireless infrastructure, particularly the sub-6 GHz 5G bands, and additional functionality for the PIH0-03 0.1 µm PHEMT process.

The NP45-11 is a 50 V, 100 mm wafer diameter process achieving 7 W/mm saturated power density with more than 65 percent power-added efficiency and 18 dB linear gain at 2.7 GHz.

For millimeter wave applications, the PIH0-03 0.1 µm PHEMT process adds monolithic PIN and vertical Schottky diodes, enabling the on-chip integration of mixers, limiters and power detectors. The PHEMT process supports applications through 100 GHz.

David Danzilio, WIN’s senior VP for technology and strategic business development, makes a compelling argument that WIN’s 0.1 µm PHEMT process is fully capable of meeting the system and component performance and cost requirements for 5G millimeter wave front-end modules.

AnritsuAnritsu introduced the first solution capable of conducting characterization of the differential noise figure of differential devices used in high-speed wireless communication systems. The solution, which integrates a new differential noise figure option into the Anritsu VectorStar™ VNAs, allows engineers to verify the receiver performance of LNAs and other devices used in the front-end of 5G and microwave back haul systems. The option is available on VectorStar models operating from 70 kHz and up to 20, 40, 70, and 110 GHz. The new differential noise figure option enhances the 2-port single-ended noise figure measurement capability of the VectorStar and allows the VNAs to measure 3- and 4-port devices in single-ended, differential and common mode operation with a variety of processing options. The Anritsu differential noise figure option incorporates the similar cold-source measurement technique as its 2-port method, which minimizes mismatch errors for improved accuracy compared to the conventional Y-factor noise source method. The new enhanced noise figure option adds the ability to perform levels of vector correction in 2- and multi-port devices for greater accuracy particularly, when mismatch is significant. The MS4640B VectorStar VNAs have the broadest coverage in a single instrument, 70 kHz to 70 GHz. Coverage can be extended to 145 GHz and 1.1 THz in broadband configurations. VectorStar is the only VNA platform capable of measuring noise figure according to Anritsu, both single-ended and differential, from 70 kHz to 125 GHz.
