MAX2605–MAX2609
45MHz to 650MHz, Integrated IF
VCOs with Differential Output
General Description
The MAX2605–MAX2609 are compact, high-performance
intermediate-frequency (IF) voltage-controlled oscillators
(VCOs) designed specifically for demanding portable
wireless communication systems. They combine monolith-
ic construction with low-noise, low-power operation in a
tiny 6-pin SOT23 package.
These low-noise VCOs feature an on-chip varactor and
feedback capacitors that eliminate the need for external
tuning elements, making the MAX2605–MAX2609 ideal
for portable systems. Only an external inductor is
required to set the oscillation frequency. In addition, an
integrated differential output buffer is provided for dri-
ving a mixer or prescaler. The buffer output is capable
of supplying up to -8dBm (differential) with a simple
power match. It also provides isolation from load
impedance variations.
The MAX2605–MAX2609 operate from a single +2.7V to
+5.5V supply and offer low current consumption. These IF
oscillators can cover the 45MHz to 650MHz frequency
range.
