EVALUATION KIT AVAILABLE MAX2605MAX2609 45MHz to 650MHz, Integrated IF VCOs with Differential Output General Description Features The MAX2605MAX2609 are compact, high-performance Small Size intermediate-frequency (IF) voltage-controlled oscillators Integrated Varactor for Tuning (VCOs) designed specifically for demanding portable wireless communication systems. They combine monolith- Low Phase Noise ic construction with low-noise, low-power operation in a Wide Application Frequency Range tiny 6-pin SOT23 package. Differential or Single-Ended Outputs These low-noise VCOs feature an on-chip varactor and feedback capacitors that eliminate the need for external Single +2.7V to +5.5V Supply tuning elements, making the MAX2605MAX2609 ideal for portable systems. Only an external inductor is Ultra-Small SOT23-6 Package required to set the oscillation frequency. In addition, an On-Chip Temperature-Stable Bias integrated differential output buffer is provided for dri- ving a mixer or prescaler. The buffer output is capable Low-Current Operation of supplying up to -8dBm (differential) with a simple power match. It also provides isolation from load impedance variations. The MAX2605MAX2609 operate from a single +2.7V to +5.5V supply and offer low current consumption. These IF Ordering Information oscillators can cover the 45MHz to 650MHz frequency range.
