Teledyne e2v HiRel yesterday announced the availability of a pair of Voltage Controlled Oscillators (VCOs) with low phase noise performance, as well as a pair of low noise amplifiers (LNAs), for low earth orbit (LEO) space and other demanding applications.
The TDVCO015 & TDVCO027 VCOs are built in GaAs InGaP Heterojunction Bipolar Transistor (HBT) process technology. They integrate resonators, negative resistance devices, and varactor diodes and offer excellent phase noise performance over temperature due to the oscillator’s monolithic structure.
The TDVCO015 VCO operates from 13.32 – 15.20 GHz and provides a typical phase noise of -115 dBc/Hz @ 100 kHz offset. The TDVCO027 operates from 23.32 – 27.34 GHz and provides a typical phase noise of -98 dBc/Hz @ 100 kHz offset. Both parts are available in a 5 mm x 5 mm, 32 lead Ceramic QFN package.
The TDLNA2626 and TDLNA2628 LNAs combine to cover 17 – 31.5 GHz frequency ranges and are built in a GaAs process technology which provides lower power consumption and high gain/bandwidth.
The TDLNA2626 LNA operates from 17 – 22 GHz and provides a low noise figure of 1.3 dB and 25 dB small signal gain. Along with P1dB of 20 dBm and IM3 levels of −55 dBc (at Pout=0 dBm/tone), it offers a compact solution in a 4 mm x 4 mm plastic QFN package.
The TDLNA2628 LNA operates from 22 – 31.5 GHz and provides a low noise figure of 1.6 dB and 23 dB small signal gain. Along with P1dB of 19 dBm and IM3 levels of −54 dBc (at Pout=0 dBm/tone), it also offers a compact solution in a 4 mm x 4 mm plastic 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. These VCOs are the first in a family of devices that can support the increasing requirements of our customers for space qualified devices... Our customers have been requesting higher frequency RF parts, and we are excited to expand our RF offerings with K-band LNAs to support applications where small size, low power consumption, and low noise figures are required in mission critical applications.
