on the characteristics of the local oscillator.
* Emissions - receiver design requires care to ensure no spurious signals are radiated by the local oscillator. Such signals can cause interference in the operation of other receivers.
* Stability - the local oscillator must produce a stable frequency with low harmonics. Stability must take into account temperature, voltage, and mechanical drift as factors.
* Power - the oscillator must produce enough output power to effectively drive subsequent stages of circuitry, such as mixers
