SYSTEMS/SUBSYSTEMS

QUAD-MxFE Platform Evaluation Boards

The Quad-MxFE System Development Platform contains four MxFE® software defined, direct RF sampling transceivers, as well as associated RF front-ends, clocking and power circuitry. The target application is phased array radars, electronic warfare and ground-based satcom, specifically a 16 transmit/16 receive channel direct sampling phased array at L-/S-/C-Band (0.1 GHz to ~5 GHz). The Rx and Tx RF front-end has drop-in configurations that allow for customized frequency ranges, depending on the user’s application.

Ultra-Low Phase Noise OCXO

KVG has launched a new revision of its ultra-low phase noise (ULPN) 100 MHz OCXO O-40-ULPN-100M series. Based on latest oscillator technology and noise improved SC-cut crystals KVG’s engineers have now achieved ultra-low phase noise performance in combination with tight frequency stability. This 100 MHz ULPN OCXO offers excellent phase noise performance near the carrier with better than -138 dBc/Hz at 100 Hz as well as a very low noise floor of -185 dBc/Hz.

Voltage Controlled Oscillators

Pasternack has just launched a new series of voltage controlled oscillators (VCOs) designed to address a wide range of electronic warfare, ECM, VSAT, satcom, radar and test and measurement applications. Pasternack’s 15 new coaxial packaged VCOs cover broad frequency bands and exhibit excellent phase noise, tuning linearity and harmonic suppression performance. These VCOs are ideal for test and measurement and signal conversion applications in transceiver circuits. VCOs generate their own output signal level and allow designers to adjust the tuning voltage, which varies the output signal oscillation frequency to get a desired signal level across a specific frequency band.

SOFTWARE

Modelithics COMPLETE+3D Library

Piconics and Modelithics announced the availability of three new 3D geometry models for the CC19T40K240G5-C, CC21T36K240G5-C and CC45T47K240G5C2 conical inductors from Piconics. These models are all included in the latest version, v21.1, of the Modelithics COMPLETE+3D Library for Ansys®HFSS™. The new models are validated through multi-substrate S-parameter measurements. Each model is validated through 67 GHz, making them well suited for broadband applications. The CC19T40K240G5-C conical inductor has an inductance value of 0.220 μH and a maximum current rating of 700 mA.

TEST & MEASUREMENT

E-Band VNA Extender

STO-12203-U6 is an E-Band VNA frequency extender that extends VNA frequency range to 60 to 90 GHz for full two-port, S-parameter testing. It is compatible with modern vector network analyzers such as the Rohde & Schwarz ZVA24, Anritsu VectorStar, Keysight PNA-X Series and Copper Mountain CobaltFx C4220. The NIST tracible calibration kit, STQ-TO-12-S1-CKIT1, is highly recommended to complete the E-Band VNA test set.

Vector Network Analyzers

Rohde & Schwarz launched the R&S ZNA originally two years ago. The newly introduced models cover frequency ranges of up to 50 GHz and 67 GHz. The R&S ZNA features excellent RF performance, including wide dynamic range and extremely low trace noise, and comes with a user-friendly, purely touch-based GUI. Its unique hardware platform offers up to four internal, phase coherent sources plus a fifth source which can be used as a second internal local oscillator or as an additional source for measurements on mixers.
