DESCRIPTION

The Model 357 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.
