GENERAL DESCRIPTION

The ADRF6620 is a highly integrated active mixer and synthesizer

that is ideally suited for wireless receiver subsystems. The feature

rich device consists of a high linearity broadband active mixer;

an integrated fractional-N PLL; low phase noise, multicore VCO;

and IF DGA. In addition, the ADRF6620 integrates a 4:1 RF

switch, an on-chip tunable RF balun, programmable RF attenuator,

and low dropout (LDO) regulators. This highly integrated device

fits within a small 7 mm × 7 mm footprint.

The ADRF6620 offers two alternatives for generating the dif-

ferential LO input signal: externally, via a high frequency, low

phase noise LO signal, or internally, via the on-chip fractional-N

PLL synthesizer. The integrated synthesizer enables continuous

LO coverage from 350 MHz to 2850 MHz. The PLL reference

input can support a wide frequency range because the divide and

multiply blocks can be used to increase or decrease the reference

frequency to the desired value before it is passed to the phase

frequency detector (PFD).

The high isolation 4:1 RF switch and on-chip tunable RF balun

enable the ADRF6620 to support four single-ended 50 Ω

terminated RF inputs. A programmable attenuator ensures

optimal RF input drive to the high linearity mixer core. The

integrated DSA has an attenuation range of 0 dB to 15 dB with

a step size of 1 dB.

The integrated high linearity DGA provides an additional gain

range from 3 dB to 15 dB in steps of 0.5 dB for maximum flexibility

in driving an analog-to-digital converter (ADC).

The ADRF6620 is fabricated using an advanced silicon-germanium

BiCMOS process. It is available in a 48-lead, RoHS-compliant,

7 mm × 7 mm LFCSP package with an exposed pad. Performance

is specified over the −40°C to +85°C temperature range.
