Transmission Line Capacitors
AVX Corp. introduced a new line of ultraminiature, thin film transmission line capacitors for high frequency links, DC blocking in the UHF range (300 MHz to 3 GHz) and other high performance RF/microwave applications. The new capacitors have a novel metal-insulator-metal (MIM) structure, copper traces for optimal circuit conductivity, a transmission line wire-bond pad, a gold-metallized backside ground and can be supplied on a variety of low loss substrates, including quartz, alumina, glass and silicon.
DC to 6 GHz Termination
BroadWave Technologies announced a new termination with an operating frequency range of DC to 6 GHz. Model 552-313-030 is a 50 Ω convection cooled RF termination designed for lab and field applications. The unit has an average power rating of 30 W with 1.5:1 maximum VSWR. The temperature range is −40°C to +40°C and RF connector is N male. Other RF connector types and genders are available in this package.

Direct Reading Phase Shifters
Cernexwave’s CDS Direct Reading Phase Shifters provide highly accurate measurement of phase shift from 0° to 360° over each full waveguide band from 26.5 to 110 GHz. They feature low VSWR, low insertion loss and low variation of insertion loss due to the rotation of the phasing section. The WR-12 Model CDS12609001 has an accuracy of less than 3°, an insertion loss of less than 1.3 dB and a VSWR of 1.3:1 all the way from 60 to 90 GHz.
High Inductance Shielded Power Inductors
Coilcraft’s new XAL7050 Series of high temperature power inductors is available with inductance values from 22 to 47 µH and current ratings as high as 5.5 A, with low DCR for greater efficiency. For lower inductance values, Coilcraft offers a lower-profile companion, the XAL7030, with an identical footprint and inductance range of 0.16 to 10 µH. The XAL7050 features RoHS-compliant tin-silver (96.5/3.5) over copper terminations and offers a maximum reflow temperature of 260°C. COTS Plus tin-silver-copper and tin-lead terminations are also available.
60 to 90 GHz Block Down-Converter
Model SNG-12-01 is a full E-Band block down-converter. Its primary function is to extend the testing capability of low cost, low frequency noise figure meters. It also allows noise figure testing of E-Band devices without a noise figure meter, using the Y-factor method. The block down-converter is also versatile for use with various other applications. With a low cost design, Model SNG-12-01 is an affordable expansion to mmWave labs that do not have the budget for large scale equipment.
Relay Controlled Programmable Attenuators
Fairview Microwave Inc. has introduced a new line of relay controlled programmable attenuators that offer accurate and stable performance with very low harmonic distortion (IMD) and cover multiple RF frequency bands down to DC. They are popular for use in military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, telecommunications and automatic test equipment (ATE). Typical applications include signal conditioning and level control, matching impedances of sources and loads and measuring the gain or loss of two-port devices.

MMIC Surface Mount Directional Coupler
Mini-Circuits’ EDC10-183+ is a 10 dB directional coupler that operates from 6 to 18 GHz packaged in MCLP 4 x 4 mm, 24-lead package. It provides excellent coupling flatness over a broad bandwidth and good return loss. This coupler also provides a quadrature phase shift between the signal at the through port and coupler port. Manufacturing using GaAs technology, this model results in relatively high repeatablility in performance.
1.8 GHz 2 Wire 1:1 Transformer
Need a very low insertion loss balun (1 dB max) with 23 dB return loss and 2 GHz BW? The MRFXF 6713 in MiniRF’s 0.15 x 0.15 package is the right choice. Do not settle for a lab queen; obtain proven repeatable products from MiniRF that still provides excellent and phase amplitude between ports.
