AD6633RF/IF射頻/中頻RFID的射頻混頻器規(guī)格書PDF中文資料

AD6633屬于RF/IF射頻/中頻RFID的射頻混頻器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD6633射頻混頻器射頻混頻器又稱混頻器，這些器件具有三個(gè)端口，用于改變兩個(gè)輸入信號的頻率。射頻混頻器是一些無源或有源器件，可用于對信號進(jìn)行上下變頻。特征包括射頻類型、頻率、混頻器數(shù)、增益、噪聲系數(shù)、輔助屬性、電流和電壓。頻率范圍為 0 至 90 GHz，混頻器數(shù)為 1、2、3 或 4。

GENERAL DESCRIPTION

The AD6633 is a multichannel, wide bandwidth digital upconverter (DUC) with crest factor reduction (CFR) technology, which is available in 4-channel or 6-channel versions. It processes 20-bit baseband input data and generates 18-bit, wideband, real, or complex output data at up to 125 MSPS. This rate is suitable for driving digital-to-analog converters (DACs) at the first intermediate frequency (IF) directly.

FEATURES

4 or 6 wideband digital upconverter channels

VersaCREST crest reduction engine reduces demands on

external power amplifiers

One 20-bit complex input port (I, Q interleaved), shared

among 4 or 6 processing channels

output port for interleaved I and Q

All-pass phase equalizer filters (meets IS-95 requirements)

Programmable RAM coefficient FIR filters (RCF) with

resampling

FIR interpolating filters, 2 per channel

Fifth-order interpolating CIC filter, 1 per channel

Full complex NCO, 32-bit tuning resolution (fine), worst spur

better than ?105 dBc, 1 per channel

Complex FIR filter for frequency equalization or additional

filtering

Output automatic gain control

Full complex composite NCO, 6-bit tuning resolution

16-bit/8-bit MicroPort (Intel? or Motorola? mode)

Serial control port (SPI?- or SPORT-compatible)

3.3 V I/O and 1.8 V core supplies

JTAG boundary scan

User-configurable, built-in, self-test (BIST) capability
