The LG I oscillator is a small lightweight OCXO with a fixed output frequency between 25 MHz and 130 MHz. This unit provides good frequency stability over temperature (ovenized version), phase noise floor performance to -170 dBc/Hz and acceleration sensitivity to 2E-10/g per axis. A non-ovenized version is available when low power consumption is a requirement and the frequency stability over temperature specification is not critical. The package is a rugged nickel-plated machined aluminum case (1.58” x 1.58” x 0.8”) and includes thru hole mounting in 4 places. The RF output is provided through a field replaceable SMA(f) connector and the supply voltage through solder pins on the opposite side. The small size and low-g options make this unit well suited for airborne and missile applications where good dynamic performance is required. A low noise voltage regulator is included to minimize power supply line related spurious signals. Please contact technical staff to discuss custom requirements.
