RF Os c illa t o r w it h Bu ffe re d Ou t p u t s

Keeping the resonant tank circuit’s real component less

than one-half the magnitude of the negative real com-

ponent ensures that oscillations will start. After start-up,

the oscillator’s negative resistance decreases, primarily

due to gain compression, and reaches equilibrium with

the real component (the circuit losses) in the resonant

tank circuit. Making the resonant tank circuit reactance

tunable (e.g., through use of a varactor diode) allows

for tuneability of the oscillation frequency, as long as

the os c illa tor e xhib its ne g a tive re s is ta nc e ove r the

desired tuning range. See Figures 3 and 4.

The negative resistance of the MAX2620 TANK pin can

be optimized at the desired oscillator frequency by

proper selection of feedback capacitors C3 and C4.

For example, the one-port characteristics of the device

are given as a plot of 1/S11 in the Typical Operating

Characteristics. 1/S11 is used because it maps inside

the unit circle Smith chart when the device exhibits

negative resistance (reflection gain).
