New Portable Signal Generator
GED completed development of a portable RF Signal Generator Ranging from 1 to 2 GHz with 100kHz Resolution. The generator is fully
PC-programmable and features programmable pre-set frequencies, amplitude control, disable outputs, automatic reference detect and many other features making it extremely versatile.
This is the newest member of our diverse family of frequency sythesizers.

Description
LMFX_SXXX is a series of frequency translators, using PLL technique to translate any input frequency from
8KHz to 200MHz to a specific output frequency from 1MHz to 800MHz.
Up to 4 different input frequencies could be locked to a high quality SAW or Crystal voltage controlled oscillators.
Feature
- Single 5V or 3.3V power supply
- Optional HCMOS or single ended PECL input signal
- Comp. PECL output, or HCMOS output option for below 200MHz
- Low output jitter
- Lock signal alarm
- Control voltage monitor output
- 1.0" x 0.8" x 0.25" Surface Mount Package.
Application
SONET/SDH, DWDM, FDM, ATM
