500.000 MHz
Voltage Controlled Crystal
Oscillator (VCXO)
Description:
KVG’s new VCXO-S500-LF is an exceptional
500 MHz high performance ‘Voltage
Controlled Crystal Oscillator’ (TCXO) offering
Low Phase Noise (LPN) and Low GSensitivity (LGS) by usage of special
packaged 3rd overtone crystal.
The part comes with a robust metal can
package with SMA connector and feedthrus
for supply voltage and tuning voltage input.
The low Gsensitivity makes it a preferred part
for any vehicle mounted applications.
