The ShockLine MS46500B series of two- and four-port vector network analyzers (VNAs) is now available in models for testing through E-band frequencies from 55 to 92 GHz. The firm also announced 20- and 40-GHz options for the VNAs. The analyzers provide dynamic range of 120 dB through 40 GHz. The two- and four-port versions use the same software with a powerful graphical user interface (GUI) for manual test environments.

Flexible/twistable waveguide sections are available in rectangular waveguide (WR) sizes from WR-137 to WR-28 for use through 40 GHz. These “flexguide” transmission lines employ helically wound silver-coated brass strips surrounded by a flexible, durable neoprene sleeve and terminated with brass flanges. Insertion loss is as low as 0.07 dB while typical VSWR ranges from 1.05:1 to 1.35:1. The waveguide are available in standard lengths, including 12, 24, and 36 in.

The ProxAnt TL 1.0 is a combination antenna and proximity sensor designed for commercial use with portable mobile computing and communications devices, such as laptop computers operating at WLAN, Wi-Fi, and LTE frequencies. It includes a seven-band antenna and proximity sensor integrated circuit (IC) on the same flexible printed circuit board (PCB). The antenna carrier measures 60.0 × 11.2 × 4.2 mm; the proximity sensor has a footprint of 13.0 × 8.8 mm. The sensor detects when a user is close and reduces transmission power to the antenna, to reduce the specific absorption rate (SAR). The sensor also detections motion to avoid a false trigger.

A pair of antenna/receiver modules serves as drop-in solutions for GPS and GNSS receiver functions in Internet of Things (IoT) and machine-to-machine (M2M) wireless applications. The SMT devices measure 9.0 × 9.0 × 1.8 mm with low current consumption. Model M10578-A2 for GPS applications operates on supplies from 2.8 to 4.2 V dc with out-of-band rejection of unwanted signals ranging from 43 to 54 dB. Model M10578-A3 for GPS, GLONASS, BEIDOU, and Galileo applications, is housed in a similar package with the same compact footprint, including an LNA and temperature-compensated crystal oscillator (TCXO).

Built for harsh operating environments, model SYM-R352HW+ is a surface-mount-technology (SMT) frequency mixer capable of broadband frequency translation with low loss. It operates with RF and local oscillator (LO) frequencies from 10 to 2500 MHz and provides an intermediate-frequency range of 10 to 500 MHz. With 6.5-dB typical conversion loss, the Schottky-diode-based triple-balanced mixer is designed for +17 dBm LO power. The RoHS-compliant mixer achieves typical third-order intercept point (IP3) of +23 dBm and exhibits 40 dB isolation between ports. The hermetic ceramic quad mixer measures 0.38 × 0.50 × 0.23 in. and is well suited for cellular infrastructure applications where printed-circuit-board (PCB) real estate is scarce. It handles operating temperatures from -40 to +85°C.
