Synthesizer/Upconverter Cuts Phase Noise At X-Band

Jan. 28, 2010

Model SYN152 is an X-band direct frequency synthesizer/upconverter from Trak that multiplies input signals by two, three, four, and seventeen to produce output signals at L-band. It accepts UHF input signals at -6 dBm and delivers L-band output signals with as much as +4 dBm output power. It provides selectable L-band output ports with fast LVTTL switching and harmonics of only -65 dBc. The phase noise ranges from -129 dBc/Hz offset 10 Hz from the carrier to -148 dBc/Hz offset 1 MHz from the carrier. The compact hermetic unit measures just 5.46 x 3.74 x 0.41 in. and is ideal for airborne applications.
