MAX2622 Datasheet | Maxim Integrated

Description Features o Fully Monolithic o Guaranteed Performance o On-Chip 50Ω Output Match o Wide Choice of Frequencies 855MHz to 881MHz (MAX2622) 885MHz to 950MHz (MAX2623) 947MHz to 998MHz (MAX2624) o +2.7V to +5.5V Single-Supply Operation o Low-Current Shutdown Mode o Smaller than Modules (8-Pin µMAX Package) MAX2622/MAX2623/MAX2624 The MAX2622/MAX2623/MAX2624 self-contained voltage-controlled oscillators (VCOs) bine an integrated oscillator and output buffer in a miniature 8-pin µMAX package. 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 matched on-chip to 50Ω. The MAX2622/MAX2623/MAX2624 operate from a +2.7V to +5.5V supply voltage and require only 8m A of supply current. In shutdown mode, the supply current is reduced to 0.1µA.
