AK1572

The AK1572 is a frequency mixer with a built-in VCO and fractional-N frequency synthesizer for applications that require high linearity in frequency conversion. The mixer section is different from the single-ended input.
It consists of a dynamic output circuit, with inputs from 690MHz to 4000MHz and outputs from 20MHz to 1000MHz. Current consumption and analog performance can be adjusted by the resistor connected to the BIAS pin. Mixer section Operates with a power supply voltage of 4.75V to 5.25V.

On the other hand, the local can generate 262.5MHz to 4400MHz by the built-in VCO, fractional-N synthesizer and local divider, which can be supplied to the mixer and output from the terminal to the outside.
The AK1572 frequency synthesizer can power down the internal VCO and combine it with an external VCO to generate a local frequency. Power down the VCO and frequency synthesizer to You can also drive the mixer with Cull. The VCO and frequency synthesizer block operate with a power supply voltage of 2.7V to 3.6V or 4.75V to 5.25V. The CPU interface is 24-bit serial data and operates with an interface voltage of 2.7V to 5.25V.
