Microwave IC voltage controlled oscillators

January 31st, 2013, Published in Articles: EngineerIT

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 3,5 GHz to 13,9 GHz, offers a wide frequency tuning range and complements ADI’s leading PLL synthesizer 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 utilise 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.
