MyMaxim SubscriptionsProduct Details
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 driving 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.

Description
The MAX2605-MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices' performance and require no additional support circuitry. Both signal outputs use SMA connectors to facilitate connection to RF test equipment.
These EV kits are fully assembled and tested. Their oscillation frequencies are set to approximately the midrange of the respective VCOs.
Features
- Easy Evaluation
- Complete, Tunable VCO Test Board with Tank Circuit
- Low Phase Noise
- Fully Assembled and Tested
