Abstract
This application note discusses applying the oscillator of the SA602A in
low power mixer applications. The SA602A consists of a Gilbert cell mixer,
a buffered emitter follower oscillator, and RF current and voltage regulator.
The simplicity of the oscillator affords many configurations which may be
easily implemented to achieve good performance at frequencies to
500 MHz.
