New microwave IC portfolio is extended with family of high-performance voltage controlled oscillators

October 30, 2012 // By Paul Buckley
Analog Devices, Inc. has introduced a new family of microwave ICs, the ADF55xx series voltage controlled oscillators (VCOs), for point-to-point (PtP), instrumentation/ test equipment and satellite communication applications.

Featuring the industry’s leading phase-noise performance, the new ADF55xx VCO series covers a frequency range from 3.5 GHz to 13.9 GHz, offers a wide frequency tuning range and complements ADI’s leading PLL synthesiser portfolio.

 The new microwave IC series comprises six parts: ADF5508, ADF5509, ADF5510, ADF5530, ADF5582 and ADF5584. Designed with GaAs MMIC technology, the new ADF55xx VCOs utilize a push-push VCO architecture which can generate both the main output as well as the half-frequency output.  The devices feature best-in-class VCO phase-noise performance of –116 dBc/Hz at 100 kHz offset at 8 GHz, which allows these parts to meet the demanding requirements of applications such as microwave PtP communications links. The VCOs are packaged in small 32-lead 5-mm x 5-mm LFCSP and operate from either a 3-V or 5-V supply.

Availability and Pricing
The ADF5508, ADF5509, ADF5510, ADF5530, ADF5582 and ADF5584 are packaged in a 32-lead 5-mm x 5-mm LFCSP is sampling now and are priced at $14.73 each in 1,000 quantities.
