Kuhne’s latest development is the “KU LNA 750850 A-WG.” Its WR112 RF-input enables a low-loss connection to waveguides resulting in a noise figure of typ. 0.7 dB (upper half band) and typ. 0.8 dB (lower half band). In its frequency range from 7.5 to 8.5 GHz, the LNA offers a high gain of 65 dB. Together with a high linearity (P1dB = 13 dBm, IP3 = 23 dBm), the LNA hence shows a very high dynamic range. Available now.

Signal Hound’s Spike™ software now includes noise figure analysis. Noise figure analysis is one of the most useful metrics for RF test engineers, characterizing the noise contributions of an electrical system, as well as the individual electrical components within the system. Spike’s new analysis mode performs noise figure measurements quickly and accurately. Signal Hound is proud to offer this as part of its free software package that comes with all Signal Hound spectrum analyzers.
Multi-layer Circuit Board Prepreg Material
Panasonic Corp. launched R-5410, halogen-free ultra-low transmission loss multi-layer circuit board prepreg material. This leading-edge product is especially well suited for automotive mmWave radar and 5G wireless communication base station applications. R-5410 enables multi-layer antenna constructions using industry-standard circuit board lamination processes and equipment which increases the flexibility of high frequency circuit board designs, improves the efficiency of antenna performance and reduces material and processing costs.
Richardson RFPD Inc. announced the availability of Ethertronics WLAN antennas which use specific technology in a trace configuration to provide high performance. This antenna has unique features enabling limited range RF tuning. Ethertronics antennas requires a smaller design keep-out area, carry lower program development risk which yields a quicker time-to-market, without sacrificing RF performance.
TEST & MEASUREMENT
Digitizer & AWG Cards
For all 65 different PCIe digitizer and signal generators, Spectrum Instrumentation released a driver for the Nvidia Jetson development kit that is based on an embedded ARM processor. The Nvidia Jetson consists of an ARM CPU and a CUDA-based GPU for high performance parallel processing, as well as one PCIe slot e.g. for a Spectrum M2p.5968 digitizer card as shown. This small but powerful combination is able to sample eight signals in parallel with 125 MS/s.
