VDI introduces new mini-VNA extenders

Virginia Diodes Inc. introduced new mini vector network analyzer extension modules, with one quarter of the volume of earlier models. These smaller modules are reduced in size but yield the same industry leading performance as the original designs. This makes them extremely attractive for applications such as probe stations and antenna ranges.

Vishay on display at IMS 2014

At IMS 2014, Vishay will be highlighting its VJ HIFREQ series and VJ QUAD HIFREQ series of surface-mount multilayer ceramic chip capacitors (MLCCs). Offering high self resonance and a low dissipation factor of = 0.05 % in the 0402, 0603, and 0805 case sizes, devices in the VJ HIFREQ series are optimized for filter and matching networks, and amplifier and DC blocking circuits in high-frequency commercial applications. The MLCCs reduce signal loss and energy consumption in power amplifier modules, VoIP networks, cellular base stations, GPS systems, and satellite, WiFi (802.11), and WiMAX (802.16) wireless communication. The VJ HIFREQ series features broad working voltages from 25 VDC to 250 VDC and wide capacitance ranges from 1 pF to 1.5 nF.
