Description

Luff Research is pleased to introduce a new frequency synthesizer for sensitive converter applications.  The TLSD units operate from 4 to 12 GHz (in bands) and provide excellent spectral quality.  Typically better than -90 dBc/Hz at X-band @10 kHz off the carrier.

This unit is housed in an EMI enclosure with filtered connectors for minimum radiation.

This unit is extremely flexible, providing customer selectable interfaces of RS232, RS422 and RS485.  There is also a provision for multiple units on one buss.

This low cost frequency synthesizer offers high performance in a unit with proven quality and reliability.
