Description
This document describes the specifications for the F1792
Wideband, Gain-Settable, Zero-Distortion^TM Flat-Noise^TM, RF to
IF Downconverting Mixer.
The F1792 offers very low power consumption with excellent
linearity. In addition to this the F1792 has four dynamically
adjustable gain settings. The F1792 performance is exceptional
across an extremely broad range of RF and IF frequencies. All of
this makes it ideal for a myriad of applications including:
• 2G/3G/4G/5G/Multimode Remote Radio Units
• Point to Point µWave Backhaul systems
• Broadband Repeaters
• Public Safety Infrastructure
• Any radio system operating between 400 MHz and 4000
MHz
Competitive Advantage
F1792 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 radio card
applications, even allowing for dynamic adjustment of gain to
maximize performance on the fly. The extremely wide RF and IF
bandwidths are achieved using a fixed BOM, all RF matching is
internal to the device. The F1792 can function with as little as -6
dBm LO power. It also features a channel shutdown mode for
ease of integration into high order TDD systems.
