F1792
F1792 is RF Wideband Gain-Settable Downconverting Mixer manufactured by IDT.
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 petitive 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 d Bm LO power. It also features a channel shutdown mode for ease of integration into high order TDD systems.
