GENERAL DESCRIPTION

This document describes the specifications for the

IDTF0552 1710MHz to 2050MHz dual path Sampling

Intermediate Frequency (SIF) Receiver ideal for Multi-

mode, Multi-carrier BaseStation Receivers. Refer to the

Part # Matrix below describing the frequency coverage of

the complete series. This series of devices covers all

UTRA bands up to 2.7 GHz and offers significantly better

Noise and Distortion performance than currently

available solutions. IF frequencies up to 450 MHz are

supported.

The IDTF0552 SIF provides 29dB gain and offers 47dB

gain adjustment in 1dB steps designed to operate with

a single 5V supply. Nominally, the device offers +45

dBm Output IP3 using 450mA of ICC. Alternately one

can configure the device in low current (LC) mode to

reduce power consumption to < 1.9 Watts.

This device is packaged in a 10x10 68-pin Thin QFN

with 50 ohm single-ended RF input and 200 ohm

differential IF output impedances for ease of

integration into the receiver lineup. The EvKit is

configured to match the 200 ohm differential IF output

to 100 ohms differential for a broad range of IF center

frequencies per the application drawings on page 51.

COMPETITIVE ADVANTAGE

IDT’s Zero-DistortionTM mixer in combination with

interstage filtering and IDT’s proprietary FlatNoiseTM

DVGA improves system SNR to the point where the

external SAW filter can be eliminated. Both IP3O & NF

are kept virtually flat while gain is backed off, enhancing

SNR significantly under high level interferer conditions,

and greatly benefiting 2G/3G/4G Multi-Carrier IF

sampling receivers. In addition, total power consumption

is reduced by ~35% compared to conventional solutions.



No external SAW is needed



Reduced Power Consumption by 35%



NF and OIP3 virtually flat for first 17 dB gain

reduction

The fast-settling, parallel mode gain step of 1.0 dB

coupled with the excellent differential non-linearity allow

for SNR to be maximized further by targeting the

minimum necessary gain in small, accurate increments.

The matched output does not require a terminating

resistor, thus the gain and distortion performance are

preserved when driving Bandpass Anti-Alias filters.
