Phase-locked oscillators offer stability in high-reliability use

January 11, 2016 // By Graham Prophet
From RF and microwave component specialist Link Microtek is a line of high-performance phase-locked coaxial resonator oscillators that are particularly suitable for use in high-reliability applications such as military satellite-communications systems, where stability and accuracy are of paramount importance.

Manufactured by L3 Narda-MITEQ, the ruggedly constructed BCO series oscillators feature high-Q ceramic resonators and can be specified with output frequencies ranging from 100 MHz to 4 GHz for fundamental configurations and 4 to 16 GHz for multiplied configurations.

The devices can be phase locked to either an external 1 to 200 MHz reference source or to the internal TCXO crystal reference. Phase noise typically ranges from -70 dBc/Hz at 10 Hz offset from carrier to -150 dBc/Hz for a 10 MHz offset. Available with operating voltages from 5.2 to 15 VDC, the BCO series oscillators have an input impedance of 50 Ohms and a nominal load VSWR of 1.5:1.

These compact devices weigh less than 100g and have maximum dimensions of 57.2 x 57.2 x 15.3 mm, excluding the female SMA connectors used for the RF inputs and outputs. All units are supplied fully burnt-in and temperature tested.
