Up Converter Mixer with
AK1575
Fractional-N Frequency Synthesizer and VCO
1. Overview
AK1575 is the up-converter mixer with fractional-N frequency synthesizer and integrated VCO.
AK1575 is targeted at the application that requires a high linearity performance in frequency
conversion. The mixer block is comprised of the differential input and the differential output. Input
frequency range is from 20MHz to 500MHz and output frequency range is from 690MHz to 4000MHz.
The current consumption and the analog performance can be adjusted by a resistance connected to
BIAS pin. The power supply voltage of mixer covers 4.75 to 5.25V.
The local signal output frequency range is from 262.5MHz to 4400MHz generated by internal VCO,
synthesizer and divider. Not only a local signal is supplied to an internal mixer, but also can be taken
to outside. A power supply voltage range of VCO/synthesizer is 2.7V to 3.6V or 4.75V to 5.25V.
The CPU interface is 24bit serial data and its voltage is ranging from 2.7V to 5.25V
