Product Details
The inductor and varactor elements of the tank circuits are integrated on-chip, greatly simplifying application of the part. In addition, the center frequency of oscillation and frequency span are factory preset to provide a guaranteed frequency range versus control voltage. An external tuning voltage controls the oscillation frequency. The output signals are buffered by an amplifier stage (easily matched to 50Ω), using only capacitors to provide higher output power and isolate the devices from load impedance variations.
The MAX2622/MAX2623/MAX2624 operate from a +2.7V to +3.3V supply voltage and require only 9mA of supply current. In shutdown mode, the supply current is reduced to 0.1µA.

Description
The MAX2622/MAX2623/MAX2624 evaluation kits (EV kits) simplify evaluation of the MAX2622/MAX2623/MAX2624 VCOs. These kits enable testing of the devices' RF performance and require no additional support circuitry. The signal output uses an SMA connector to facilitate the connection to RF test equipment.
The MAX2622 EV kit is assembled with the MAX2622 and incorporates output matching components optimized for an RF frequency of 868MHz. The MAX2623 EV kit is assembled with the MAX2623 and incorporates output matching components optimized for an RF frequency of 917MHz. The MAX2624 EV kit is assembled with the MAX2624 and incorporates output matching components optimized for an RF frequency of 973MHz.
Features
- Easy Evaluation of MAX2622/MAX2623/MAX2624
- +2.7V to +3.3V Single-Supply Operation
- RF Output Matched to 50Ω
- All Critical Peripheral Components Included
