Miniature Frequency Synthesizer Operates To 12.5 GHz

摘要

Applications in communications, radar, and instrumentation can take advantage of the SLSM5 family of frequency synthesizers. These synthesizers operate to 12.5 GHz and cover as much as octave bandwidths. They boast phase noise of -95 dBc/Hz offset 10 kHz from the carrier at the X-band and spurious performance starting at -60 dBc. With 1-kHz steps and frequency controlled via an RS-485 interface, the SLSM5 synthesizers are system-friendly components. They operate on either an external 10-MHz input or an internal temperature-controlled crystal oscillator (TCXO). Only a single +5.0-V supply is needed to power this 2.5-x-2.5-x-0.6-in. unit.
