Luff Research, Inc. has introduced an exciting new line of miniature frequency synthesizers designated SLSM3. These units offer very high fundamental frequency of operation with up to 7 GHz fundamental operation and to 14 GHz with a × 2 multiplier. The SLSM3 synthesizers also offer very high tuning bandwidths. Octave tuning ranges are available in standard units. These synthesizers offer excellent performance and can provide unparalleled economy to many system applications. At a typical resolution of 1 MHz, these synthesizers offer very good spectral quality. Operating on either an external or internal reference frequency these units offer very good phase noise and excellent spurious response. The SLSM3 synthesizers conveniently operate on a single low voltage power supply and are serially controlled via a 3-line bus. They are housed in a miniature 2.5 inches× 2.5 inches× 0.6 inches rugged connectorized housing and are system ready.
