AD6600
AD6600/AD6620
Diversity Receiver Chipset
HIGHLY INTEGRATED CHIPSET
REDUCES SIZE AND COST OF BASE
STATION RECEIVERS
Analog Devices’ innovative Diversity Receiver
chipset delivers two IF-to-baseband diversity
channels in a compact, comprehensive solution
that incorporates Automatic Gain Control,
Received Signal Strength Indicator, highresolution Numerically Controlled Oscillator
and digital filtering on-chip.
The chipset comprises Analog Devices’ AD6600
dual-channel IF sampling analog-to-digital
converter and AD6620 dual-channel decimating
receiver chip. Configured with the appropriate
external components, it can address a variety of
air interface standards, including GSM, CDMA,
IS136 and PHS, as well as proprietary modulation schemes for paging systems and wireless
fixed access receivers.
Based on Analog Devices’ next-generation
receiver architecture, the Diversity Receiver
replaces sensitive analog filters with digital
filters for significant cost and size reductions.
Complete reference designs show the optimal
layout for reducing noise and minimizing
cross-channel coupling.
Analog Devices’
streamlined, highly
integrated solution
reduces component
count, cost and
time-to-market for
diversity receivers.
FEATURES
• Dual-channel: integrates two IF-to-baseband diversity channels
• Fewer discrete components: cuts manufacturing costs
• On-chip digital filters eliminate need for high-cost analog IF filter for
reduced bill of materials cost
• Accepts common intermediate frequencies for cellular, PCS, paging
(70-250 MHz Ain)
• Small outline, surface-mount plastic packaging (44-pin TQFP, 80-pin
PQFP): reduces receiver size, simplifies micro- and pico-cell designs
• High dynamic range: 80 to 100+ dB, depending on channel bandwidth,
sample rate and filter characteristics
• Easily interfaces to general-purpose DSPs
• Complete radio reference designs reduce your engineering investment
