TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Design Of A Complete RF Downconverter Module For Test Equipment

     The example module and its constituent parts were designed and simulated with AWR Design Environment software using circuit- and system-level analyses. The integration of the downconverter within a mechanical outline influences the layout of the individual radio blocks.

  • Load Transient Response – Enhancing Loop Stability Testing

    Ensuring stability in power supply design requires validating switching converter stability through frequency loop and load transient responses, aided by modern oscilloscopes for visualizing PWM signals and identifying converter effects.

  • Understanding Component EMC Testing for ICs

    If you're producing integrated circuit (IC) products for electromagnetic environments, you must test and pass all the regulatory electromagnetic interference (EMI) and safety requirements. Electromagnetic compatibility (EMC) testing is performed to ensure these components can be used in the intended environment without failing, degrading, or causing other equipment to fail.

  • VSWR Conversion To Reflected Power

    VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.

  • Measurement Setup For Phase Noise Test At Frequencies Above 50 GHz

    Recent semiconductor technologies require more of the frequency range beyond 50 GHz, especially in wideband applications, such as 802.11ad, microwave links, or automotive RADAR. Low phase noise is essential for these applications to work properly, and accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise.

TEST & MEASUREMENT SOLUTIONS

Bird offers the FH-AV-KIT, a FlightHawk™ RF Aviation Test Kit designed for avionics testing and measurement applications. This kit includes a proven antenna and cable testing functionality of the FlightHawk handheld analyzer, all necessary adapters and cabling, and Bird’s aviation testing software that allows anyone on the maintenance team to test and verify all antenna systems in a fleet.

Qorvo offers the 1800 W, 65 V, 1.0 – 1.1 GHz QPD1025L as the highest GaN transistor on the market. This discrete GaN on SiC HEMT has a package that features input pre-match resulting in ease of external board match and saved board space.

The Si894x is a galvanically isolated delta-sigma modulator which outputs a digital signal proportional to the voltage level at the input. 

Holzworth’s multi-channel RF synthesizer architecture is a complete success story. These compact, 1U high, 19in rack mountable chassis can be configured with up to 8 independently tunable channels. All integrated channels are 100% phase coherent. Holzworth has designed the multi-channel platform for integration of our HSM Series Single Channel Synthesizers to maximize channel-to-channel stability via a conductively cooled, fan-less enclosure.

The dB-3907 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3907 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

dB Control’s family of traveling wave tube amplifiers (TWTAs) features a combined frequency range of 2 to 18 GHz up to 15kW output power. dB Control utilizes our proprietary transformer fabrication, encapsulation and high-voltage potting techniques developed for demanding military applications which results in superior reliability, low cost and ease of maintenance.  Products in this series are ideal for several applications, including: test and measurement, electronic warfare (EW) simulation, RFI/EMI/EMC Testing, electronic countermeasures (ECM), and antenna pattern and radar-cross section measurements.

Radar simulation systems (i.e., RF sources and/or receivers) must perform to an exacting minimum standard if they are to accurately prove the field worthiness of EW systems.

Pentek offers the Quartz® Model 6003 high-performance Quartz eXpress Module (QuartzXM) based on the Xilinx Zynq UltraScale+ RFSoC FPGA. The RFSoC FPGA integrates eight RF-class A/D and D/A converters into the Zynq’s multiprocessor architecture, creating a multichannel data conversion and processing solution on a single chip.
