(see the Typical Operating Circuit) as small a value as  
possible while still maintaining desired frequency and  
tuning range to maximize loaded Q.

There are many good references on the topic of oscilla-  
tor design. An excellent reference is “The Oscillator  
as a Reflection Amplifier, an Intuitive Approach to  
Oscillator Design,” by John W. Boyles, Microwave  
Journal, June 1986, pp. 83–98.

Output Matching Configuration  
Both of the MAX2620’s outputs (OUT and OUT) are  
open collectors. They need to be pulled up to the sup-  
ply by external components. An easy approach to this  
pull-up is a resistor. A 50resistor value would inher-  
ently match the output to a 50system. The Typical  
Operating Circuit shows OUT configured this way.  
Alternatively, a choke pullup (Figure 1), yields greater  
output power (approximately -8dBm at 900MHz).  
µMAX  
for maximum power transfer. Using this data and stan-  
dard matching-network synthesis techniques, a match-  
ing network can be constructed that will optimize power  
output into most load impedances. The value of the  
inductor used for pullup should be used in the synthe-  
sis of the matching network.  
When maximum power is required, use an inductor as  
the supply pull-up, and match the inductor’s output  
impedance to the desired system impedance. Table 1  
in the Typical Operating Characteristics shows recom-  
mended load impedance presented to OUT and OUT
