Analog – New family of high-performance voltage-controlled oscillators (ADF5508)Oct 30 2012 - Passives [More Passives Articles]
Analog Devices 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 3.5GHz to 13.9GHz, 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 -116dBc/Hz at 100kHz offset at 8GHz, 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 5mm x 5mm LFCSP and operate from either a 3V or 5V supply, says the company.
