RF Oscillator with Buffered Outputs
_________________General Description
The MAX2620 combines a low-noise oscillator with two
output buffers in a low-cost, plastic surface-mount,
ultra-small μMAX package. This device integrates func-
tions typically achieved with discrete components. The
oscillator exhibits low-phase noise when properly
mated with an external varactor-tuned resonant tank
circuit. Two buffered outputs are provided for driving
mixers or prescalers. The buffers provide load isolation
to the oscillator and prevent frequency pulling due to
load-impedance changes. Power consumption is typi-
cally just 27mW in operating mode (V CC = 3.0V), and
drops to less than 0.3μW in standby mode. The MAX2620
operates from a single +2.7V to +5.25V supply.
