Model 1152 Phase Locked Oscillator
  |
Designed to replace
crystal oscillator LO chains for microwave receivers and transmitters
used by Amateur Radio operators. Now there is an inexpensive alternative
to those unstable high frequency crystal oscillators which drift constantly,
allowing precise receiver/transmitter frequency settings using a stable external 10
MHz reference oscillator like a TCXO, Oven Controlled Oscillator
or a Rubidium Oscillator.
The Model 1152 outputs one of 8 selectable frequencies listed
in Table 1 and Table 2. |
