18 GHz Microwave PLL Synthesizer

Data Sheet

ADF41020

FEATURES

GENERAL DESCRIPTION

18 GHz maximum RF input frequency

Integrated SiGe prescaler

Software compatible with the ADF4106/ADF4107/ADF4108

family of PLLs

2.85 V to 3.15 V PLL power supply

Programmable dual-modulus prescaler

8/9, 16/17, 32/33, 64/65

Programmable charge pump currents

3-wire serial interface

The ADF41020 frequency synthesizer can be used to implement

local oscillators as high as 18 GHz in the up conversion and

down conversion sections of wireless receivers and transmitters.

It consists of a low noise, digital phase frequency detector

(PFD), a precision charge pump, a programmable reference

divider, and high frequency programmable feedback dividers

(A, B, and P). A complete phase-locked loop (PLL) can be

implemented if the synthesizer is used with an external loop

filter and voltage controlled oscillator (VCO). The synthesizer

can be used to drive external microwave VCOs via an active

loop filter. Its very high bandwidth means a frequency doubler

stage can be eliminated, simplifying system architecture and

reducing cost. The ADF41020 is software-compatible with the

existing ADF4106/ADF4107/ADF4108 family of devices from

Analog Devices, Inc. Their pinouts match very closely with

the exception of the ADF41020’s single-ended RF input pin,

meaning only a minor layout change is required when updating

current designs.
