RF Dual Wideband Gain-Settable
Downconverting Mixer
F1192B
Datasheet
GENERAL DESCRIPTION
This document describes the specifications for the
IDTF1192B Dual Wideband, Gain-Settable, Zero-
DistortionTM Flat-NoiseTM, RF to IF Downconverting Mixer.
The F1192B has been optimized for GSM systems as
well as those utilizing LTE.
The F1192B offers very low power consumption with
excellent linearity. In addition to this and the four
dynamically adjustable gain settings, the F1192B
performance is exceptional across an extremely broad
range of RF and IF frequencies. All of this makes it
ideal for myriad applications including:
• 2G/3G/4G/5G/Multimode Remote Radio Units
• High order MIMO systems, µcells, picocells, DAS
• Point to Point µWave Backhaul systems
• Broadband Repeaters
• Public Safety Infrastructure
• Any radio system operating between 400 MHz and
4000 MHz
COMPETITIVE ADVANTAGE
F1192B offers maximum performance and flexibility at
minimum power consumption. The unique and patented
settable-gain feature allows it to be used in a very wide
variety of radiocard applications, even allowing for
dynamic adjustment of gain to maximize performance on
the fly. The extremely wide RF and IF bandwidths are
achieved with a fixed BOM with all internal matching.
The device can function with as little as -6 dBm LO
power and with independent channel shutdown modes
for ease of integration into high order TDD MIMO
systems.
