DESCRIPTION
The Model 335 is a ceramic packaged Voltage
Controlled oscillator offering reduced size and
enhanced stability. The small size means it is
perfect for any application. The enhanced
stability means it is the perfect choice for today’s
communications applications that require tight
frequency control.
