Teledyne e2v HiRel Electronics of Milpitas, CA, USA (part of the Teledyne Defense Electronics Group that provides solutions, sub-systems and components to the space, transportation, defense and industrial markets) has announced the availability of a pair of voltage-controlled oscillators (VCOs) with low-phase-noise performance for low earth orbit (LEO) space and other demanding applications.
Fabricated in gallium arsenide (GaAs) indium gallium phosphide (InGaP) heterojunction bipolar transistor (HBT) process technology, the TDVCO015 and TDVCO027 integrate resonators, negative-resistance devices, and varactor diodes and are said to offer excellent phase-noise performance over temperature due to the oscillator’s monolithic structure.
The TDVCO015 operates at 13.32–15.20GHz and provides a typical phase noise of −115dBc/Hz @ 100kHz offset. The TDVCO027 operates at 23.32–27.34GHz and provides a typical phase noise of −98dBc/Hz @ 100kHz offset. Both are available in a 5mm x 5mm, 32-lead ceramic QFN package.
“With the need for higher and higher frequencies, many of our customers have been requesting the ability to provide RF synthesizers in various higher-frequency bands,” says VP & business development manager Mont Taylor. “These VCOs are the first in a family of devices that can support the increasing requirements of our customers for space-qualified devices.”
Devices are available for ordering and shipment now, from Teledyne e2v HiRel or an authorized distributor.
