Digi-Key Corporation Expands Cree Product Line

Digi-Key Corporation Expands Cree Product Line to Include Gallium Nitride (GaN) HEMTs for Microwave Applications

Digi-Key Corporation and Cree, Inc. announced today that Digi-Key is now stocking Cree’s Gallium Nitride (GaN) HEMT transistors for general purpose microwave applications. Digi-Key’s portfolio of Cree offerings encompasses SiC power components, SiC MESFETs, high-brightness and high-power LEDs, and now, GaN HEMT transistors.

Cree’s GaN HEMT general-purpose transistors, in power levels ranging from 10W to 90W, are ideal for microwave applications that require high efficiency, multi-octave bandwidth performance. These transistors offer high frequency performance to 6GHz, high gain, and low parasitic capacitance within small package footprints. This enables smaller, lighter, and more energy efficient systems, often with fewer amplifier components, than required with other microwave transistor technologies.

“We are pleased that Digi-Key is stocking Cree GaN HEMT transistors,” said Jim Milligan, Cree’s director of RF and microwave products. “Digi-Key has the distribution expertise and industry channels to help accelerate the adoption of our GaN HEMT technology.”

Digi-Key President and COO Mark Larson commented, “Relied upon by engineering and purchasing communities for product selection and availability, Digi-Key is committed to providing its customers with the latest and most sought-after technologies. To that end, we are very pleased to make Cree’s GaN HEMT transistors available to our customers.”

Tiger TGD-A1 Couplers from Link Microtek

Directional couplers reduce costs without compromising performance

Link Microtek, the specialist supplier of RF and microwave components, has expanded its range of Tiger Microwave products with the addition of the TGD-A1 series of directional couplers.
These competitively priced devices are manufactured to exceptionally high quality standards and provide excellent performance for a wide variety of military and commercial applications over the frequency range 500MHz to 18GHz.

Equipped with SMA-type female connectors as standard, the directional couplers feature insertion losses as low as 0.4dB and VSWR values ranging from 1.2:1 to 1.6:1, while operating temperature range is specified as -55 to 85degC. They have a directivity of 10dB, 12dB or 20dB and a frequency sensitivity of +/-0.7dB or +/-1.0dB.

Available with coupling values of 6, 10, 20 or 30dB, the TGD-A1 series couplers are particularly suitable for use in microwave test systems and for integration into mobile-phone infrastructure or satellite communications equipment.
