AD6633RF/IF射频/中频RFID的射频混频器规格书PDF中文资料

AD6633属于RF/IF射频/中频RFID的射频混频器。由亚德诺半导体技术有限公司制造生产的AD6633射频混频器射频混频器又称混频器，这些器件具有三个端口，用于改变两个输入信号的频率。射频混频器是一些无源或有源器件，可用于对信号进行上下变频。特征包括射频类型、频率、混频器数、增益、噪声系数、辅助属性、电流和电压。频率范围为 0 至 90 GHz，混频器数为 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

Two 18-bit output ports for parallel I and Q or a single 18-bit

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
