Low Phase Noise Frequency Synthesizers
EM Research offers HFS-Series low phase noise frequency synthesizers for up/down converter mixer local oscillator applications. Ideally suited for use in ISM, GSM, WLL, and MMDS/LMDS system transceivers, these products are available as fixed frequency or externally programmable, covering the frequency range (in bands) from 40 MHz to more than 8 GHz. Product features include fast switching speeds in step sizes of 50 kHz to 2.5 MHz, typical phase noiise characteristics of 95 dBc/Hz at 10 kHz offset, 120 dBc/Hz at 100 kHz offset. Miniaturized surface-mount package size is 1.25× 1.00× 0.25. The device operates over the temperature range of 30 ° C to 70 ° C.
